Push Bar Door Lock: Types, Code Requirements and Complete Specification Guide

A push bar door lock, also called a panic bar, panic exit device, or crash bar, is the most specified egress hardware in North American commercial construction. Every controlled-access door in a building where people need to exit quickly in an emergency relies on this mechanism to work without hesitation. The exit hardware section at American Locksets carries the complete commercial push bar lineup from Von Duprin, Sargent, Falcon, and Corbin Russwin. Whether you are a contractor specifying a new building, a facility manager replacing worn hardware, or a code consultant reviewing a hardware schedule, this guide covers every push bar door lock type, the building codes that govern them, the terminology that causes most ordering errors, and how to match the right device to every door on the schedule.

Push Bar, Panic Bar, Crash Bar, Touch Bar: Clearing Up the Terminology

These terms all refer to the same category of hardware, but they describe different variants. Using the right term prevents confusion on hardware schedules and with suppliers.

Push bar: A horizontal bar mounted on the interior face of a door that retracts the latch when depressed. The broadest term covering all exit devices with a horizontal actuator.

Panic bar or panic hardware: The code-based term used in IBC and NFPA 101. "Panic hardware" is the official designation when the device is required by code as a means of egress release mechanism.

Crash bar: An informal name referring to the ability to operate the device by body impact under emergency conditions, without requiring hand grip or pressing a specific spot.

Touch bar: A specific push bar design where the push pad is a narrow horizontal bar that requires less contact area to activate. Von Duprin's touch bar design is one of the most widely specified in institutional commercial applications.

Crossbar: A full-width horizontal bar spanning the door. Von Duprin's crossbar style spans the full door width, providing activation across the broadest contact area.

Fire exit hardware: A specific classification under NFPA 80 and UL 10C for exit devices used on fire-rated door assemblies. Fire exit hardware has specific listing requirements and functional differences from standard panic hardware - covered in detail below.

When a Push Bar Door Lock Is Required by Code

This is the question every hardware specifier faces on every project, and most guides in the top search results answer it incorrectly or incompletely.

IBC Section 1010.1.9 requires panic hardware on:

• Doors serving a room or space with an occupant load of 50 or more persons in assembly or educational occupancies

• Doors serving a high-hazard occupancy regardless of occupant load

• Specific Group A (assembly), E (educational), and H (high-hazard) occupancies where the occupant load triggers the requirement

NFPA 101 Life Safety Code Section 7.2.1.7 mirrors the IBC requirement and applies in jurisdictions that adopt NFPA 101 instead of or alongside IBC.

Buildings that do not meet these thresholds are not legally required to use panic hardware - but panic hardware is frequently specified voluntarily on any commercial door where hands-free exit is desired, where high-traffic egress is anticipated, or where the facility wants to reduce the risk of a person being trapped during an emergency.

Key dimensional requirements under both codes:

• Push bar must activate the latch when a force of no more than 15 pounds is applied in the direction of egress

• Push bar must span at least 50 percent of the door width

• Push bar must be mounted between 34 inches and 48 inches above the finished floor

• ADA Section 404.2.7 requires no more than 5 pounds of force to operate the push bar on any accessible route

The 5-pound ADA requirement is stricter than the 15-pound code maximum and governs on all doors that are on a required accessible means of egress.

Four Types of Push Bar Exit Devices and When to Use Each

This is where most hardware guides fail specifiers. Knowing the four exit device types and the correct application for each prevents the most common ordering errors on commercial hardware schedules.

Rim Exit Devices

The rim exit device is the most commonly specified push bar door lock for single exterior commercial doors. The device body mounts on the surface of the door face. The latch projects from the device and engages a strike plate on the door frame. No rods, no vertical connections.

The Von Duprin 98 and 99 Series, Sargent 8800 Series, and Corbin Russwin ED5200 are the industry-standard rim exit devices for commercial applications. Von Duprin's 98 Series and 99 Series are functionally identical - the 99 Series uses a wider stile body. Both are ANSI A156.3 Grade 1 certified and UL 305 listed for panic hardware.

Rim exit devices are non-handed, which means the same device installs on left-hand or right-hand doors without modification. This simplifies stocking and reduces ordering errors on large door schedules.

Use rim exit devices on: single exterior commercial doors, primary entry and egress doors in educational and assembly occupancies, and any single door where a clean installation without exposed rods is preferred.

Surface Vertical Rod (SVR) Exit Devices

A surface vertical rod exit device uses the same horizontal push bar body as a rim device but adds a vertical rod running up the face of the door to a top latch and, on most models, a bottom rod connecting to a floor latch. The door latches at three points: the center latch from the device body, the top latch, and the floor latch.

Surface vertical rod devices are specified on paired door applications - two doors hanging in the same frame - where the inactive leaf needs to latch at the head and floor without a center strike. The Von Duprin 9927 and 9827, Sargent 8700 Series, and Corbin Russwin ED5400 are the primary SVR models for commercial paired door applications.

Use surface vertical rod devices on: paired exterior doors without a mullion, double-door openings in schools, hospitals, and government buildings where the inactive leaf must be independently latched.

Concealed Vertical Rod (CVR) Exit Devices

A concealed vertical rod device operates the same three-point latching as a surface vertical rod device, but the rods run inside the door instead of on the surface. The result is a cleaner appearance with no exposed vertical hardware on the door face.

CVR devices require a specially prepared door with internal chase routing for the rods. They are specified on architectural projects where the exposed vertical rod of an SVR device is aesthetically unacceptable - hotel lobbies, government building main entries, university administration buildings, and any project where the door face appearance is part of the design specification.

Mortise Exit Devices

A mortise exit device integrates a mortise lock body into the door, controlled by the push bar on the door face. The mortise body handles the locking function while the push bar handles egress.

Mortise exit devices are specified on primary entries where both egress function and lock security from the outside are required in a single integrated unit. They provide a broader range of functions than rim or rod devices and are more commonly specified on main building entries in healthcare, government, and institutional facilities where outside trim with cylinder control and multiple lock functions are required.

Panic Hardware vs Fire Exit Hardware: The Distinction That Governs Dogging

This is the most consequential technical distinction in push bar specification, and most commercial hardware guides get it wrong or skip it entirely.

Panic hardware (standard exit device) is listed under UL 305 for panic function. It can include mechanical dogging, which is a feature that holds the push bar in the depressed position using a hex key or cylinder, converting the device from panic mode to push-pull operation. Dogging allows the door to function as a non-latching push-pull door during business hours, removing the need for users to push the bar for routine passage.

Fire exit hardware is listed under both UL 305 (panic) and UL 10C (positive pressure fire testing) for use on fire-rated door assemblies. Fire exit hardware cannot use mechanical dogging because fire-rated assemblies require positive latching - the latch must project and engage the strike when the door closes. A dogged (latched-open) device on a fire door means the door does not latch when it closes, which fails both the NFPA 80 annual inspection requirement and the fire door assembly listing.

The practical rule: any push bar door lock installed on a fire-rated door assembly must be fire exit hardware with UL 10C listing, and it cannot have mechanical dogging enabled. If the facility needs a push-pull function on a fire door during business hours, electric dogging is the correct specification. Electric dogging holds the push bar through an electromagnetic mechanism that releases automatically on fire alarm activation, restoring the positive latching function when the fire alarm panel removes power from the dog.

For doors where outside access with key control is needed alongside the push bar egress function, the function code determines how the outside trim operates. The most common function codes:

• EO (Exit Only): No outside trim. Egress only from inside. Correct for stairwells and secondary exits.

• DT (Dogging): Push bar can be mechanically held open. Not for fire-rated assemblies.

• NL (Night Latch): Outside cylinder controls entry while push bar provides egress. Correct for main entries requiring key control.

• L (Lever): Outside lever handle provides entry access. Correct for main entries in ADA-accessible configurations.

The Von Duprin 98/99 Series, Sargent 8800 Series, and Corbin Russwin ED5200 all support these function codes. For a detailed look at how fail-safe and fail-secure functions interact with electrified exit devices, see the fail safe vs fail secure guide on this site.

ANSI A156.3 Grade 1: What the Grade Rating Means for Exit Devices

Exit devices are graded under ANSI/BHMA A156.3. Grade 1 is the only acceptable specification for commercial and institutional applications. Grade 2 applies to light commercial and residential use only.

Under ANSI A156.3, a Grade 1 exit device is tested to:

• 1,000,000 push bar cycles

• 250,000 outside trim cycles (lever, thumb piece, or pull)

• Resistance to forced entry

• Fire door compatibility testing where UL 10C listing is included

Grade 1 exit devices from Von Duprin, Sargent, and Corbin Russwin all carry ANSI A156.3 Grade 1 certification. Many lower-cost push bars sold online - including many Amazon listings - carry "UL 305" listing without ANSI A156.3 Grade 1 certification. UL 305 only covers the panic function test. ANSI A156.3 Grade 1 covers cycle durability, outside trim, and forced entry resistance. On any commercial project subject to building inspection or AHJ review, specify ANSI A156.3 Grade 1 explicitly on the hardware schedule.

Alarmed Push Bar Exit Devices: When the Alarm Is the Right Specification

An alarmed push bar door lock adds a local sounder to the exit device that activates when the push bar is depressed. The alarm sounds for a set period, typically 15 seconds to 3 minutes depending on configuration, alerting staff to an unauthorized or unexpected exit.

Alarmed exit devices are commonly specified on:

• Retail store secondary exits where shoplifting prevention is a concern

• School secondary exits where student monitoring is required

• Healthcare facility exits where patient elopement is a documented risk

• Any secondary exit where door use should be monitored but full electronic access control is not warranted

Most alarmed exit devices include a key cylinder to silence and reset the alarm, a 15-second delay arming cycle when the alarm is set, and a battery backup for locations without hardwired power available. The Detex EAX series, Von Duprin with alarm option, and Falcon alarmed devices are the primary commercial options for alarmed exit device applications.

For projects where push bar exit devices connect to a full electronic hardware access control system including electric strikes or electrified trim, hardwired monitoring and access logging replace the standalone alarm function.

Common Push Bar Specification Errors and How to Avoid Them

Twenty-four years of supplying exit hardware at American Locksets has made these patterns clear. The following errors show up repeatedly and all of them are preventable with the right specification conversation before the order ships.

Ordering standard panic hardware for a fire-rated door. The door prep, the hardware listing, and the dogging function all differ between standard panic hardware and fire exit hardware. Confirm the door's fire rating before selecting the device.

Enabling mechanical dogging on a fire-rated assembly. Mechanical dogging on a fire door is a NFPA 80 violation. If the facility wants push-pull function on a fire door, specify electric dogging with fire alarm panel integration.

Specifying a rim device on a paired door without a center mullion. Paired doors without a center mullion require vertical rod devices on the inactive leaf. A rim device needs a fixed strike plate in the center of the frame, which does not exist on a pair without a mullion.

Ordering a non-listed device on a building that will go through AHJ inspection. Many low-cost online push bars are not ANSI A156.3 Grade 1 certified. AHJ inspectors look at hardware listings. A non-compliant device fails inspection regardless of how it looks or how well it was installed.

Why American Locksets for Push Bar Door Lock Projects

A push bar exit device does not ship alone on a complete hardware schedule. It ships with outside trim, a door closer, a cylinder, and on paired doors, a coordinator and flush bolts on the inactive leaf. Getting all of it from a single authorized dealer eliminates the scheduling risk of mismatched components arriving from different sources.

American Locksets carries the complete commercial push bar lineup: Von Duprin 98 and 99 Series rim devices, 9827 and 9927 surface vertical rod devices, and the full Sargent, Falcon, and Corbin Russwin exit device families. The full selection is in the exit hardware section. For projects where push bar devices install alongside electric strikes for access control, or alongside commercial locks on other doors in the same schedule, everything ships on a single authorized dealer order with same-day shipping from multiple US warehouses.

For paired door projects, the builders hardware section covers coordinators, flush bolts, and door stops that ship alongside the exit devices.

Conclusion

A push bar door lock is the code-required egress mechanism on most commercial doors serving 50 or more occupants in assembly, educational, and high-hazard occupancies under IBC Section 1010.1.9 and NFPA 101. Rim devices cover single doors. Surface vertical rod covers paired doors. Concealed vertical rod is specified for architectural applications. Mortise exit devices integrate a full lock function with push bar egress. Standard panic hardware can be mechanically dogged. Fire exit hardware under UL 10C cannot. Dogging on fire doors requires electric dogging tied to the fire alarm panel. All commercial applications require ANSI A156.3 Grade 1 certification. ADA limits operating force to 5 pounds on accessible routes. American Locksets carries the complete push bar lineup from Von Duprin, Sargent, Falcon, and Corbin Russwin with same-day shipping.
