What Push Bar and Panic Bar Installation Actually Involves
A panic bar — also called a crash bar or exit device — is a spring-loaded horizontal bar mounted across a door that releases the latch when pushed. What looks simple from the outside involves precise alignment of the crossbar assembly, the latch bolt or mortise lock body, the strike plate, and sometimes an alarm contact or electric release. Improper installation results in doors that fail to latch completely, panic bars that bind under pressure, or hardware that does not meet NFPA 101 Life Safety Code egress requirements. Our technicians measure door thickness and backset, confirm frame condition, and select the correct exit device grade — ANSI/BHMA Grade 1 for high-traffic commercial doors — before a single hole is drilled.
Push bar door lock installation is also not a one-size-fits-all job. Hollow metal doors, aluminum storefront frames, and solid wood fire doors each require different mounting hardware, different through-bolt patterns, and different strike preparations. We carry a range of compatible exit devices and mortise lock bodies on our service vehicles so most installations are completed in a single visit without back-ordering parts.
