Sargent 68-3835 Chassis Assembly for 80 Series Exit Devices — LHR

The Sargent 68-3835 is a genuine OEM chassis assembly engineered specifically for the Sargent 80 Series exit device. Also referenced by its full part designation 12-59-28 LHR, this component serves as the core operating mechanism within the exit device body. When the push bar is depressed, the push rail transfers that force directly to this chassis assembly, which actuates the latch retraction to permit immediate, code-compliant egress. This is a Left Hand Reverse (LHR) handing configuration — refer to the handing diagram accompanying this listing for door preparation details. Replacing or restoring this chassis with a factory-correct part ensures the exit device performs to its original design specifications.
