What Panic Bar and Exit Device Service Actually Covers
Panic bars — also called crash bars or push bars — are the horizontal release bars mounted across emergency and high-traffic egress doors. When someone pushes against the bar, a latch mechanism retracts and the door swings open without requiring the user to turn a knob or handle. That single-motion release is what building codes mandate for doors serving assembly areas, schools, healthcare facilities, and any occupancy above a certain threshold of people. The device sounds simple, but inside the mechanism are precision components: the dogging hardware that holds the latch open during business hours, the push-pad actuator, the vertical rods on a surface-vertical-rod device, and — on higher-security applications — a fully integrated mortise lock exit device that adds a keyed cylinder and a multi-point latch set into the door stile itself.
A mortise lock exit device (sometimes called a panic bar with mortise lock) provides two layers of function in one trim package. From the outside, a key-operated mortise cylinder allows authorized entry. From the inside, the panic bar release works the same way any standard exit device does — no key needed to exit. Von Duprin mortise lock exit device models are among the most specified by architects and fire marshals in New Jersey commercial projects, and our team works with that product line as well as other professional-grade hardware suited to your specific door preparation. Understanding which type your doors require is step one; our technicians assess frame preparation, door thickness, and fire-rating requirements before recommending any specific unit.
