2. MOUNT ARMATURE TO DOOR
Assemble using hardware provided in the order
shown. All hardware shown must be used except
where noted.
Note that the tapered washer must be
placed with the pointed side facing away from the
door and toward the armature. It MUST be used for
proper operation.
Use hex key to tighten the arma-
ture mounting bolt. For solid core and
hollow metal doors, gently tap sex nut
into position with a rubber mallet
before mounting armature assembly.
Proper use of hardware will allow
armature to pivot slightly after securely
tightening the mounting screw. This is
normal, and necessary to allow arma-
ture to mate properly with magnet.
CAUTION:
Failure to secure armature to door may result in seri-
ous injury to door user. For proper operation, safety
and security, sex nut / bolt assembly, washers and
spacers must be assembled in the order illustrated
and securely tightened 1/8 to 1/4 turn past hand
tight.
