What Panic Bar Installation Actually Involves for Commercial Doors
A panic bar — also called a crash bar or exit device — is a spring-loaded horizontal bar mounted across an exit door that unlatches the door when pressure is applied from the inside. Simple in concept, but the installation itself involves far more than bolting a bar to a door. Our technicians evaluate door thickness, material, existing prep cuts, frame condition, and the fire or building code classification of the opening before a single screw turns. Getting this wrong means a door that does not latch correctly, a bar that sits at the wrong ergonomic height, or an exit device that fails an inspection — all outcomes that create real liability for a business owner.
The most common configurations we handle in Cranford include rim-mounted exit devices, surface vertical rod devices for double doors, concealed vertical rod assemblies, and mortise lock panic bar combinations. That last category — a panic bar with mortise lock — is particularly common in higher-security commercial settings. A mortise lock panic bar integrates a full mortise lock body into the door's edge, giving you deadbolting function on the exterior while still guaranteeing free egress from the inside. It is the right solution for a front door that needs to serve as both a secure entry point and a code-compliant exit, and it is one of the more technical installations we perform. If you are not sure which device fits your door, we will walk you through the options before any work begins.
