Preparing the door and door jamb

1
Mark centerlines
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 rein-
forcement. For dimensions for preparing metal doors,
see the W13 Template—Installation Specifications for
34HM–35HM IDH Max Mortise Locks.
1 On the door, measure and mark the height of the cen-
terline of the knob/lever from the floor (38" recom-
mended). On both sides of the door, on the door's
edge, and on the door jamb, mark the horizontal cen-
terline of the lock 1 1/2" above the centerline of the
knob/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.
