Installation Instructions for 45H & 47H Mortise Locks
Finishing the installation
16 Install mortise case faceplate
Note: Most locks ship with only one faceplate. The UNAB
and UNR locks ship with two faceplates each, allowing
for multiple function configurations. For AB (UNAB) and
A (UNR) function locks, use the faceplate that exposes the
locking toggle.
1 Secure the mortise case faceplate to the mortise case
with the faceplate mounting screws.
2 Check the lock for proper operation.
17 Install strike box and strike plate
1 If the door jamb has not been mortised for the strike box
and strike plate, perform these steps:
a On the door jamb, locate the horizontal centerline
of the strike (3/8″ above the centerline of the lock),
as well as the vertical centerline of the strike.
b Mortise the door jamb to fit the strike box and
strike plate.
c Drill the holes for the screws used to install the
strike box and strike plate.
2 If the strike box has a filled area, orient the
strike box so that the filled area is down.
3 Insert the strike box into the mortise in the
door jamb. Place the strike plate over the
strike box and secure the strike with the
screws provided.
4 Check the position of the auxiliary bolt
against the strike plate (or the filled area of
the strike box).
Note: The recommended gap between the
door and jamb is 1/8″.
