A door exit device, often called a panic bar or push bar, lets people leave a building with one push. Press the bar and the latch pulls back, so the door opens even in a rush. Building codes call for this hardware on many commercial doors. Under the IBC, doors serving 50 or more people in assembly and school spaces need it. The bar must cover at least half the door width and release with 15 pounds of force or less. Fire-rated doors need fire exit hardware.
Exit devices take a beating. Staff, guests, patients, and carts push them hundreds of times a day. Over time, latches stick, rods slip out of line, and dogging fails. We service top brands, including Von Duprin, Sargent, Corbin Russwin, Precision, and Falcon. We match the right device to your door, frame, and traffic. From government offices to hospitals and hotels, we keep your exits safe, secure, and ready for your next fire inspection.
Each exit device type latches in its own way, so each one needs its own fix. Rim devices latch to a strike on the frame. Mortise devices use a lock case set inside the door edge. Surface and concealed vertical rods latch at the top and bottom. Pick your hardware type below to see how we install, repair, or replace it.

Under the International Building Code, doors serving 50 or more people in assembly or educational spaces must use panic or fire exit hardware. High-hazard spaces and some electrical equipment rooms need it too. Local rules in Maryland, DC, and Virginia can add more. We can walk your building and tell you which doors need an exit device.
Many problems only need a repair. Sticking latches, loose push bars, worn dogging, and rods out of line can often be fixed with an adjustment or new parts. Replace the device if it is cracked, missing parts, no longer supported, or not listed for your door. We will tell you which option makes more sense before any work starts.
Yes. Many exit devices can be electrified. Common options include electric latch retraction, electrified outside trim, request-to-exit switches, and delayed egress. These let you lock and unlock doors on a schedule and use card readers. Delayed egress has extra code rules, so we confirm what your building allows before we install it.
