Norton Drop Plate, 3-3/4" x 9-3/4"
For use where a overhead door holder prevents normal top jamb mounting. This places the center line of the arm mounting screws at 3-1/2” from the top of the door.
Can also be used where a narrow top rail prevents the closer from being mounted directly to the door surface. This drop plate can be used to mount a closer on a top rail as narrow as 3-1/8”
