Note: If the door is a fabricated hollow metal door,
determine whether it is properly reinforced to support
the lock. If door reinforcement is not adequate, consult
the door manufacturer for information on proper
reinforcement. For dimensions for preparing metal
doors, see the G03 Template—Installation
Specifications for 35HG and 35HBV Mortise Locks.

centerline of the lever from the floor (38″
recommended). On both sides of the door, on the
door’s edge, and on the door jamb, mark the
horizontal centerline of the lock 1 1/2″ above the
centerline of the lever.
Note: If the door is a LH or RH door, mark the inside of
the door. If the door is a LHRB or RHRB door, mark the
outside of the door.
2 On the door’s edge and door jamb, mark the vertical
centerline of the lock.
3 Measure and mark the backset (2 3/4″ standard) from
the vertical centerline on the door’s edge. On both
sides of the door, mark the vertical centerline of the
lock.
4 On the door jamb, mark the horizontal centerline of
the strike 3/8″ above the horizontal centerline of the
lock.
