STEP 4 - LOCK & ARMATURE ALIGNMENT
With the electro-magnet energized and the armature fully engaged, position the Lock so that the door
is snug against stops and then tighten the #14 Sheet Metal Screws or the ¼ #20 machine screws
securely.
Using the 3/16” dia. holes in the mounting plate behind the electro-magnet as a physical template, drill
two .159 dia. holes (# 21 drill) and tap the frame for # 10/32 machine screws, or drill two 11/64” dia.
holes in the frame for # 190 sheet metal screws. Secure the mounting plate with the #10 screws and
lock washers.
THE USE OF THESE #10 SCREWS IS IMPORTANT, as they provide resistance to shear rotation
and assure maximum system holding efficiency of the system.
