If your building fills with people, the door they run to in an emergency has one job: open the instant a body hits it. That is what a panic bar does. Push, and the latch lets go, no thumbturn to find, no lever to twist, no key to fumble for in the dark. For a lot of GTA commercial buildings it is not a nice-to-have either. Ontario’s code requires it on the right doors, and an inspector who finds the wrong hardware on an exit can hold up your occupancy.
Panic bars also get abused. Staff prop them, tenants complain they rattle, the latch stops catching, and someone quietly disables the alarm. Every one of those shortcuts turns a life-safety device into a liability. This guide walks through what these devices actually are, the different types, what Ontario code requires, how to keep security without breaking egress, and when a worn bar should be repaired versus replaced.
What is a panic bar?
A panic bar is a spring-loaded horizontal bar mounted across the inside of an exit door that releases the latch when you push it, letting the door open with a single motion. The trade name is an exit device. Because the bar spans most of the door, anyone moving toward it, even in a crowd, presses some part of it and the door opens. No prior knowledge of the hardware is needed, which is the whole point during an evacuation.
The device does two things at once. It holds the door latched and secure when nobody is pushing, and it dumps that latch the moment pressure lands on the bar. That combination, secure until the instant you need out, is why exit devices sit on nearly every code-required egress door in commercial buildings, from a small assembly room to a warehouse loading area.
Panic bar, crash bar, push bar, exit device: same thing?
The names get used loosely, and that trips up a lot of buyers. Most of the time people mean the same piece of hardware. The one distinction worth keeping straight is between a true code-listed exit device and a plain push bar with no latch mechanism, which is really just a rail you shove.
| Term | What people usually mean | Notes |
|---|---|---|
| Panic bar | A code-listed exit device that releases a latch when pushed | The common name for the whole device |
| Crash bar | Same device, older nickname | Named for people crashing into doors during a rush to exit |
| Exit device | The industry and code term | What you will see on spec sheets and standards |
| Push bar / push pad | Either the actuating part of an exit device, or a plain non-latching bar | A plain push bar with no latch is not a code exit device |
| Panic exit device / panic hardware | A device listed for panic egress | Listed to a panic standard, not necessarily fire rated |
So a panic bar, a crash bar, and an exit device are the same thing. A push bar might be the touchpad on that device, or it might be a decorative rail on a non-latching door. When a door needs to meet code for egress, you want a listed exit device, not a bar that only looks the part. If you are sorting out what belongs on each opening, our broader guide to commercial door hardware maps how exit devices fit alongside closers, hinges, and locks.
How a panic bar works
Press the bar and an internal mechanism pulls the latch back. Two actuator styles show up in the field. A touch bar (also called a push pad) is the flat, wide paddle that makes up most of a modern device, and it depresses slightly when pushed. A crossbar is the older round or square rail that pivots inward. Both do the same job. Touch bars are now the norm because they are lower profile and harder to snag.
Many devices also offer dogging. Dogging holds the latch retracted so the door works as a simple push/pull during business hours, which saves the latch and the closer from constant slamming. Mechanical dogging uses a hex key or cylinder to hold the pad down. Not every door is allowed to be dogged, and that limit is where panic hardware and fire exit hardware part ways, covered below.
The four exit device configurations
Exit devices are grouped by how and where they latch. Picking the wrong configuration is one of the most common and expensive mistakes on a door order, because the device has to match the door, the frame, and whether the opening is a single or a pair. Here are the four you will meet.
| Configuration | How it latches | Best for | Watch out for |
|---|---|---|---|
| Rim | A surface latch on the door face catches a strike on the frame | Single doors, and pairs when paired with a removable mullion | Simplest and most economical to service; needs a strike or mullion to latch against |
| Surface vertical rod (SVR) | Rods run up and down the door face to latch top and bottom | Pairs without a mullion, and openings where a center post is not wanted | Bottom rods collect dirt and fall out of adjustment; a top-rod-only setup avoids that |
| Concealed vertical rod (CVR) | Same top and bottom latching, rods hidden inside the door | Clean look on higher-end entrances and pairs | Harder and costlier to adjust; door usually has to be prepped for it |
| Mortise | A mortise lock body pocketed into the door edge does the latching | Heavy-traffic single doors needing strong security and trim options | Requires a mortise pocket in the door; more involved to install and replace |
On a pair of doors you have a choice: run a removable mullion down the middle so both leaves can use simple rim devices, or skip the mullion and use vertical rod devices on both leaves. A mullion gives you stronger, cheaper-to-maintain rim hardware but adds a post you have to remove for wide moves. Vertical rods keep the opening clear but need more upkeep. For openings on steel doors, our guide to hollow metal doors covers how the door prep and reinforcement affect which devices you can hang.
Panic hardware versus fire exit hardware
This is the distinction that catches property managers off guard, and getting it wrong can void a fire door assembly. Both look almost identical on the wall. The difference is what they are listed for and one feature: dogging.
| Feature | Panic hardware | Fire exit hardware |
|---|---|---|
| Listed to | UL 305 (panic) | UL 10C and UL 305 (fire and panic) |
| Used on | Non-fire-rated egress doors | Fire-rated door assemblies that also need panic egress |
| Mechanical dogging | Allowed (latch can be held retracted for push/pull) | Not allowed; the door must positive-latch at all times |
| How to get push/pull | Mechanical dogging | Electric latch retraction that re-latches on a fire alarm signal |
| Factory label | Marked Panic Hardware | Marked Fire Exit Hardware |
A fire door has to stay latched so it can hold back fire and smoke, which is why fire exit hardware cannot be mechanically dogged. If you want a fire door to act as a push/pull during the day, the only compliant route is electric latch retraction that automatically throws the latch back when the fire alarm sounds. Put a dogged panic device on a fire door and you have defeated the assembly. Check the label stamped on the device and match it to the door. Our fire-rated door checklist for emergency exits and the deeper look at Ontario Building Code fire door requirements both go into how the hardware, closer, and label have to work together.
When does Ontario code require a panic bar?
Ontario’s requirement lives in the Building Code under door release hardware. The general rule is that an exit door has to open from the inside with a single releasing motion, without a key, a special device, or any specialized knowledge. That alone rules out deadbolts and thumbturns on a lot of exits. Panic hardware becomes mandatory on specific higher-occupancy doors.
| Ontario Building Code 3.4.6.16 | What it says |
|---|---|
| Single-motion release | Exit doors must open from the inside with one releasing operation, no keys or special knowledge (dwelling units and some restricted rooms excepted) |
| Panic hardware required on | Exit doors from assembly occupancies with an occupant load over 100; doors from exit stairs where the building occupant load is over 100; exit doors from high-hazard industrial occupancies of any size |
| Device reach | The actuating bar must extend across at least half the door width |
| Opening force | Once the latch is released, the door must open with no more than 90 N applied at the release device |
| Mounting height | Release hardware mounted between 900 mm and 1,100 mm above the finished floor |
Assembly occupancies are the ones that catch most owners: restaurants and bars, banquet and event spaces, places of worship, theatres, gyms and studios, schools, and similar rooms where people gather. Cross the occupant-load threshold and the exits need panic hardware. High-hazard industrial spaces need it regardless of size. If you are not sure how your space is classified or what your occupant load actually is, that is worth confirming before you order hardware, because it drives the whole spec. You can read the requirement in the province’s own text of the Ontario Building Code (O. Reg. 332/12), and our checklist on whether your current doors are up to Ontario Building Code is a practical starting point.
Panic bars and accessibility
Panic hardware happens to be barrier-free friendly. Ontario’s accessibility rules and the barrier-free provisions of the Building Code call for operable hardware that does not need tight grasping, pinching, or wrist twisting. A push bar is operated by pushing, so it clears that bar easily, which is one reason exit devices show up on accessible routes. The related requirement is force: the effort to release and swing the door has to stay within code limits so someone with limited strength can still get out. Our piece on handicap accessible door width and the overview of accessibility requirements for storefront doors cover the clearances that go hand in hand with the hardware. The Government of Ontario also publishes plain-language accessibility rules for businesses and non-profits.
Outside trim: how people get back in
An exit device always lets people out. What happens on the outside is set by the trim you pair with it. This is where you tune security without ever touching egress, because the bar on the inside is unaffected by any trim choice.
| Outside trim / function | What it does | Typical use |
|---|---|---|
| Exit only (blank / dummy) | No outside handle; the door cannot be opened from outside | Dedicated emergency exits and rear doors |
| Night latch (key retracts latch) | A key pulls the latch to enter; no lever | Staff-only back doors |
| Lever or knob with key | Locked or unlocked lever, key overrides | Main entrances and doors used both ways |
| Pull with key cylinder | Fixed pull, key controls the latch | Entrances wanting a clean pull look |
The takeaway that saves owners from illegal fixes: you never need to chain, bar, or deadbolt an exit to keep people out, because the right outside trim already does that while the inside stays free to open. If your team is propping a rear exit for convenience, the answer is usually a lever trim or a controlled entry, not a defeated bar. For a wider look at controlling entrances without choking egress, see our guide to commercial property door security upgrades and the deeper dive on commercial door locks.
Electrified exit devices and access control
Exit devices tie into access control cleanly because you can add electric functions on the outside and to the latch without ever affecting the free push to get out. These are the common electrified options.
| Option | What it adds |
|---|---|
| Electric latch retraction (ELR) | Motor or solenoid holds the latch back for scheduled push/pull, and it re-latches on a fire alarm on rated doors |
| Request to exit (REX) | A switch signals the access system that someone left, so a valid exit does not read as a forced door |
| Latch monitoring | Reports whether the latch is actually thrown, useful on secured perimeter doors |
| Alarmed exit device | A built-in local alarm sounds when the bar is pushed, deterring casual misuse of a fire exit |
| Delayed egress | Holds the door briefly after the bar is pushed, only where the code specifically permits it, with signage and alarm release |
Alarmed devices are the polite way to solve the propped-exit problem: staff learn fast that the horn sounds, and the exit stays fully functional for a real emergency. Delayed egress is more specialized and only legal in certain occupancies and conditions, so it should be specified by someone who knows the code for your space. Automatic operators can also be layered on for accessibility, which we cover in the context of automatic versus manual doors.
Choosing the right exit device for your building
The right device is the one that matches your door type, your traffic, whether the opening is fire rated, and how you need to handle entry from outside. Here is a starting point by building type. Treat it as a guide, not a substitute for a spec against your actual doors.
| Building or opening | Common device | Why |
|---|---|---|
| Restaurant, bar, or event space main exit | Rim device, fire exit hardware if the door is rated | High occupant load triggers panic hardware; rim is durable and easy to service |
| Retail storefront entrance | Rim device with lever trim on narrow-stile aluminum | Free exit plus keyed entry, sized for a slim aluminum door |
| Office suite fire-rated stair door | Fire exit hardware, no dogging, or ELR that re-latches | Door must positive-latch to protect the stair |
| Warehouse or industrial rear exit | Rim or vertical rod, exit-only trim, often alarmed | Secure from outside, free from inside, deters propping |
| Pair of doors, no center post wanted | Surface or concealed vertical rod on both leaves | Latches top and bottom without a mullion |
| Pair of doors, maximum durability | Removable mullion with rim devices | Stronger, cheaper to maintain than vertical rods |
Grade matters too. Exit devices are rated under the ANSI/BHMA A156.3 standard, and Grade 1 is the heavy-duty tier, tested to 500,000 cycles. On any door that sees steady traffic, Grade 1 is worth the difference, because a bargain device on a busy exit fails early and you pay twice. You can review how the standard defines exit devices on the Builders Hardware Manufacturers Association reference for A156.3. When a new opening is in play, our guide to choosing the right commercial door pairs the door and the hardware decision.
Common panic bar problems and what causes them
Exit devices are simple, but they take abuse, and a device that does not latch is both a security hole and, on a fire door, a code violation. Most complaints trace back to a short list of causes.
| Symptom | Likely cause | Typical fix |
|---|---|---|
| Door will not latch when closed | Misaligned strike, sagging door, or worn latch | Realign strike, address hinges, replace latch parts |
| Vertical rod door catches only at the top or not at all | Rods out of adjustment or bottom rod fouled with debris | Adjust rods, clean or convert to top-rod-only |
| Bar feels stiff or sticks down | Dry mechanism, bent pad, or stuck dogging | Clean and lubricate, free the dogging, replace the pad |
| Loud slam every time the door closes | Closer out of adjustment working against the device | Tune the closer valves |
| Rattle or drafts around the exit | Worn weatherstrip or loose device screws | Reseal and re-secure the device |
| Exit propped open with no alarm | Missing or disabled deterrent, wrong trim for the use | Add an alarmed device or the correct outside trim |
A slamming exit is often the closer, not the bar. If the door bangs or drifts, our step-by-step on adjusting a commercial door closer and the look at what it costs to ignore a failing closer both help. A grinding or dragging door usually points at hinges or the frame, which we cover in why a commercial door grinds.
Repair or replace the exit device?
Most exit device issues are repairs. The device is modular, and parts like pads, latches, rods, strikes, and trim can be swapped without pulling the whole unit. Replacement makes sense when the device is obsolete, when a non-rated device sits on a fire door, or when the housing itself is damaged.
| Lean toward repair | Lean toward replace |
|---|---|
| Device is a current Grade 1 model with parts available | Device is discontinued and parts are hard to source |
| Problem is a strike, rod, pad, or trim | The internal chassis is worn or damaged |
| Latch and label are correct for the door | A non-fire device is on a fire door, or the label is gone |
| One-off adjustment after heavy use | Repeated failures on a high-traffic exit |
If a device keeps failing on a busy door, upgrading to a heavier grade usually costs less over a few years than repeated service calls. Our general framework on repair versus replacement for commercial doors applies here too. And a device that will not latch on a security or fire door is not a wait-and-see item; that is a same-day call, which is exactly what emergency commercial door repair is for. If you are unsure whether it can wait, our guide on when to call for emergency door repair helps you triage.
Installation and code considerations
An exit device has to be installed to its listing, mounted at the right height, and matched to the door and frame prep. On a fire door, the device, the closer, the hinges, and the frame all have to be part of a labeled assembly, and swapping in the wrong part can void the label. That is why exit hardware on a rated opening is not a general handyman job. New openings or occupancy changes can also trigger a permit, which we cover in when GTA businesses need permits for door work.
Two things are worth confirming before any install: the door swing and the device match. Egress doors on busy routes generally swing in the direction of travel, so the device and hinges have to be handed correctly. And the device configuration has to suit the door, whether that is a slim aluminum storefront, a hollow metal door, or a rated stair door. If a rated door or frame is damaged, the exit is only as good as the assembly around it, and that may mean fire-rated door repair or full fire-rated door replacement before the hardware is worth anything.
Maintenance schedule for exit devices
Exit hardware is life-safety hardware, so it earns a regular check. A few minutes each quarter catches the small problems before they become a failed latch or a failed inspection. Fire doors and their hardware also carry their own periodic inspection expectation.
| Interval | Task |
|---|---|
| Monthly (staff walk) | Push each exit, confirm it opens freely with one motion and latches when closed; check nothing is blocking or propping it |
| Quarterly | Check strike alignment, rod adjustment on vertical rod devices, dogging function, and tighten loose fasteners |
| Semi-annual | Clean and lubricate the mechanism, inspect the pad and trim, verify the closer is working with the device |
| Annual | Full service, and on fire doors confirm the label, positive latching, and self-closing as part of a fire door inspection |
What panic bars cost in the GTA
Device pricing spans a wide range because a light import bar and a Grade 1 commercial device are not the same product, even if they look similar. As a market reference, economy panic bars sell in roughly the sixty to one hundred fifty dollar range at Canadian retail, while commercial Grade 1 rim devices commonly run a few hundred dollars, and vertical rod, mortise, fire-rated, and electrified devices climb from there. Those are hardware-only figures. Installed cost depends on the labor below.
| Cost driver | Effect on price |
|---|---|
| Device grade and configuration | Grade 1, vertical rod, mortise, and fire-rated cost more than a basic rim device |
| Fire rating | Fire exit hardware and matched assemblies cost more than non-rated |
| Electrification | ELR, alarms, and access-control tie-ins add hardware, wiring, and power |
| Door prep | A new mortise pocket, concealed rods, or reinforcing an aluminum stile adds labor |
| Outside trim | Keyed levers and cylinders cost more than exit-only trim |
| Single vs pair | Pairs need two devices or a mullion, roughly doubling hardware |
For an accurate number on your doors, a quick assessment beats a guess, because the device, the door, and the trim all move the price. Our overview of commercial door installation cost in Toronto gives more context on how door work is priced in this market.
Frequently asked questions
What is a panic bar?
A panic bar is a horizontal bar mounted across the inside of an exit door that releases the latch when pushed, so the door opens with a single motion. Its formal name is an exit device. It keeps the door secure when idle and lets people out instantly during an emergency without a key or special knowledge.
What is another name for a panic bar?
Crash bar, push bar, panic exit device, and exit device all refer to the same hardware. Exit device is the term you will see in codes and on spec sheets. Crash bar is the older nickname, coined for people rushing and crashing into exit doors during an evacuation.
Is there a difference between a panic bar and a push bar?
Sometimes. A push bar can mean the push pad on a real exit device, or it can mean a plain non-latching bar that only pushes the door open. A true panic bar releases a latch and is listed for egress. A decorative push bar with no latch is not a code-compliant exit device.
What is the difference between panic hardware and fire exit hardware?
Panic hardware is listed to UL 305 and can be dogged so the latch stays retracted for push/pull. Fire exit hardware is listed to UL 10C and UL 305, cannot be mechanically dogged, and must keep the door positive-latched so it can hold back fire and smoke. Fire doors require fire exit hardware.
Which doors need a panic bar in Ontario?
Under the Ontario Building Code, panic hardware is required on exit doors from assembly occupancies with an occupant load over 100, on doors from exit stairs where the building occupant load is over 100, and on exit doors from high-hazard industrial occupancies of any size. Your occupancy classification and occupant load decide it.
Does every exterior commercial door need panic hardware?
No. Panic hardware is tied to occupancy type and occupant load, not simply to being an exterior door. Many small commercial exits use a lever lockset that still opens from inside with one motion. Once you cross the code thresholds, or the door is a required exit from a high-occupancy or high-hazard space, panic hardware applies.
Can a panic bar be locked?
The inside push is never locked; that would defeat egress and violate code. What you lock is the outside. With the right trim, the door is secure from outside and completely free from inside. You control entry, never exit.
Can you lock a panic bar from the outside so people cannot get in?
Yes, and that is the correct approach. Exit-only trim, a keyed lever, or a night latch keeps the outside secured while the inside bar still opens on a push. Chaining or deadbolting an exit to keep people out is both unsafe and illegal.
Do panic bars prevent theft or break-ins?
An exit device with proper outside trim secures the door from outside as well as a good lockset does. The weak point is usually people, not the hardware: a propped or defeated exit is the real risk. An alarmed device discourages misuse while keeping the exit fully functional.
What is dogging on a panic bar?
Dogging holds the latch retracted so the door acts as a push/pull during business hours, which reduces wear and slamming. Mechanical dogging uses a hex key or cylinder. Fire doors cannot use mechanical dogging; they must positive-latch, so push/pull on a fire door is achieved with electric latch retraction that re-latches on a fire alarm.
How high should a panic bar be mounted?
The Ontario Building Code calls for release hardware to be mounted between 900 mm and 1,100 mm above the finished floor. Manufacturers set the bar within that band. Correct height also matters for accessibility, so the bar is reachable by everyone using the exit.
Are panic bars accessible and AODA friendly?
Yes. A push bar is operated by pushing, so it needs no tight grasping, pinching, or wrist twisting, which is exactly what barrier-free hardware rules call for. The companion requirement is opening force, which has to stay within code limits so the door is usable by someone with limited strength.
What is the difference between rim, vertical rod, and mortise exit devices?
A rim device latches to a strike on the frame and is the simplest to service. A vertical rod device latches at the top and bottom of the door, which suits pairs without a center mullion, in either surface or concealed form. A mortise device uses a lock body pocketed into the door edge for heavy-duty single doors.
Can a panic bar be added to an existing door?
Often yes, if the door and frame suit it. A rim device is the easiest retrofit. Vertical rod and mortise devices need more door prep, and a fire door must keep a matched, labeled assembly, so the retrofit has to preserve the rating. An assessment confirms what the specific door can take.
How long do panic bars last?
A Grade 1 device tested to 500,000 cycles under ANSI/BHMA A156.3 can last many years on a busy door with basic maintenance. Lighter devices on heavy doors wear far faster. Replace when parts are no longer available, the chassis is worn, or the device no longer latches reliably.
Why will my panic bar not latch?
The usual causes are a misaligned strike, a sagging door pulling the latch out of line, worn latch parts, or on vertical rod devices, rods out of adjustment or a fouled bottom rod. A device that will not latch is a security and, on a fire door, a code problem, so it should be corrected promptly.
Do I need a permit to install panic hardware?
Swapping like-for-like hardware usually does not, but a new opening, a change of use, or work that affects a fire separation can trigger a permit or inspection. When occupancy or exiting changes, confirm the requirement before the work so the exit passes inspection the first time.

Suggested designer graphics (AI image models are unreliable for labelled diagrams, so build these by hand): a cutaway diagram of a rim vs surface vertical rod vs concealed vertical rod vs mortise device; a labelled panic vs fire exit hardware comparison card (UL 305 vs UL 10C, dogging); an Ontario Building Code 3.4.6.16 quick-reference card (occupancy triggers, 900 to 1,100 mm mounting, 90 N opening force); and an exit device maintenance checklist graphic.
Where an exit device ties into an access control system, it often works alongside an electric strike or electrified hardware that controls entry while keeping egress free.
Exit hardware usually sits on a rated door, so it helps to see how fire rated door ratings match the fire separation.
