The DM2 adapter plate is designed to allow easy replacement of DY2 interlocks with DM interlocks. Because of the large number of DY2 interlocks installed in the field we recognized a need for a mounting plate that will accommodate the DM interlock. The 316 Series DM interlock will bolt to the DM2 adapter plate with 3/8-16 x 1-3/4” bolts.

The DM2 Adapter Plate is made from zinc plated steel and can be bolted or welded to your door or door jamb.
