What Goes Wrong With Panic Bars and Exit Devices
Panic bars — also called crash bars or push bars — are mechanical assemblies with more moving parts than most building owners realize. The most common failure points include a worn or broken latch bolt that no longer extends fully into the strike plate, a crossbar that has sagged or seized from years of heavy use, a corroded or snapped return spring that leaves the bar permanently depressed, and a misaligned strike caused by door settling or repeated forced use. In high-traffic San Antonio buildings — schools near NISD campuses, event venues around the Alamodome, or downtown bars subject to nightly crowd pressure — these parts wear out faster than the manufacturer's projected cycle count.
Internal rod linkages can also fail, especially on double-door setups where a vertical-rod device controls both the top and bottom latches. When only one rod releases, the door appears locked even after the bar is pushed, creating a dangerous exit blockage. Electrical strikes and electrified exit devices add another layer of complexity: a wiring fault, a failed solenoid, or an access-control miscommunication can render the door permanently locked or permanently unsecured. Our technicians are experienced with both mechanical and electrified exit-device systems and carry a range of replacement components on every service vehicle.
