A door must open and relatch
Von Duprin introduced the first panic bar in 1908 and is part of Allegion. Cairn services its rim, mortise and vertical rod exit devices on commercial doors, including hardware that sticks, fails to relock or no longer works correctly.
On a fire-rated door, replacement is like for like so the door retains its rating. We examine the existing device, door movement and latching before proposing repairs or new hardware. Some conditions require a fire door inspector or fire marshal.

Work that keeps exit doors operating
The installed device type and door rating determine the repair or replacement approach. We inspect the entire operating assembly before specifying work.
Install an exit device
We assess the door and selected hardware, install the device and test opening and relatching with the manager.
Rekey compatible trim
We can rekey the cylinder on the outside of an exit door so old keys stop working, while leaving the exit device in place.
Repair a sticking panic bar
We inspect a bar that sticks or a latch that fails to reset, checking the device and door movement before proposing repair.
Replace worn exit hardware
When replacement is needed, fire-rated door hardware is replaced like for like, with the existing door rating taken into account.
Hardware warranty and service status
Cairn installs and services Von Duprin hardware but is not an authorized Von Duprin dealer. Hardware carries the manufacturer's warranty, with terms depending on the product. Cairn's 12-month workmanship warranty covers qualifying labor on exit devices we install or repair.
