Kawneer doors usually use Dor-o-matic Panic Exit Devices

Kawneer doors usually use Dor-o-matic Panic Exit Devices.  And to be more specific they usually use the Dor-o-Matic 1670 or Dor-o-Matic 1760 Touch Bar Styled Exit Panic Devices, but we also see the the 1490 and 1590″, and the obsolete 1390’s.  The use these two panic devices because of there rugged construction and there inexpensive price tag.   There are a few things that usually break on these exit devices.   One is the Dor-o-Matic Pinion Gear PB5,  the Dor-o-Matic Top Latch Rod Assembly PB130 and the Dor-o-Matic Dogging Assembly Kit PBX-16..  If you are having problems with the Key Cylinder, most likely a tooth is missing from the Pinion Gear PB5.   If your bottom rod is dragging on the floor, then the problem is in the Top Latch Rod Assembly PB130.   If you are unable to lock your door open with the 7/32″ allen wrench key, then your dogging assembly kit is most likely stripped.
