Every commercial building has emergency exits — but not every emergency exit is actually ready for an emergency. Doors secured with knobs, levers, or keyed deadbolts create dangerous bottlenecks the moment a crowd needs to get out. The solution mandated by building code and proven by decades of fire safety data is an exit device, commonly called a panic bar: a horizontal push rail that releases the door latch with a single forward motion — no keys or handles required. In the sections below, you’ll find everything a business owner needs to understand before scheduling a panic bar installation, from code requirements to hardware types to what a licensed locksmith evaluates on-site.
What Is a Panic Bar and How Does It Work?
A panic bar — also referred to as a crash bar or exit device — is a spring-loaded latching mechanism mounted horizontally across an emergency exit door. Pushing the bar inward retracts the latch bolt and allows the door to swing open, even under crowd pressure. No locks to twist, no knobs to fumble with, and no keys required from the inside. The three components every exit device assembly shares:
- The crossbar (touchpad or rail): Mounted at mid-height, 34–48 inches off the floor per ADA guidelines.
- The latch bolt: Engages the door frame strike plate when closed; the crossbar retracts it.
- The backset assembly: Transfers mechanical energy from the push-bar to the latch retraction.
At Phoenix Valley Wide Locksmith, our commercial hardware team has completed panic bar installations across hundreds of openings in Maricopa County. Find us on Google Maps to confirm our service area.
Building Code Requirements for Panic Bar Installation
The International Building Code (IBC) and NFPA 101 establish when panic hardware is mandatory:
- Assembly occupancies (restaurants, theaters, event venues): Required when occupant load exceeds 49 persons.
- Educational occupancies: Same 49-person threshold.
- High-hazard occupancies: Required regardless of occupant load.
Our commercial locksmith services always begin with a code compliance review. Business owners in Scottsdale, Mesa, and across the Valley should verify their local fire marshal’s adopted code edition before every inspection.
Pro Tip: Any change in occupancy use — converting storage into a customer-facing area — may change your hardware requirements. Schedule a commercial door hardware audit whenever a space changes use.
Panic Bars vs. Deadbolt Security: The Right Hardware for Each Door
A deadbolt — keyed from outside and operated by a thumbturn lock inside — is correct for office interiors, server rooms, and storage. Its deep bolt throw resists forced entry. However, a deadbolt on a required egress door is a code violation in most U.S. jurisdictions because it requires deliberate manipulation from the inside.
A panic bar trades exterior key control for guaranteed one-motion interior release. For dual-purpose doors, a rim device with keyed exterior trim preserves compliant egress while allowing controlled entry. Our door hardware specialists evaluate each opening individually. Need lock installation on interior doors at the same time? We can scope both in a single visit.

The Panic Bar Installation Process: Step by Step
- On-site measurement — Door thickness, stile width, and floor clearance determine the right device model.
- Frame and strike preparation — Strike plate position must be precise; misalignment causes latch drag and premature wear.
- Mounting and torque calibration — Fasteners torqued to specification prevent shifting under repeated use.
- Force and function testing — ANSI/BHMA A156.3 requires no more than 15 lbs of push force. Every installation at Phoenix Valley Wide Locksmith is force-gauge verified before sign-off.
- Alarm integration — Integral alarm horns wired to the building’s fire panel or configured to local-only alert.
Retrofitting an older lever handle or thumbturn lock? Our team handles retrofits without full door replacement in most cases. If you also need a lock rekey on other doors, we coordinate both in one visit.
Residential Applications: Home Safety and Accessible Egress
Homeowners with aging family members, young children, or residents with mobility limitations increasingly install residential panic hardware on rear doors and garage entries. These devices eliminate the need to operate a deadbolt or thumbturn lock under stress — a critical home safety consideration. Our residential locksmith team in Phoenix can assess your egress points and recommend the right hardware. If you’re planning broader home security upgrades, this is a natural addition to the scope.
