9. On the interior side of the door, center the mortise
bolt mounting plate over the through hole. Secure the
plate in position with the two screws provided.
10. Slide the thumb turn stem into the mortise bolt
body and hand thread the mortise bolt trim plate onto
the mounting plate. If the trim plate does not align
with the mounting plate, you may need to loosen the
screws and adjust the location slightly.
Note:
The thumb turn stem is designed to fit doors in ex-
cess of 4” thick. Measure and cut this stem so that it reach-
es to the approximate center of the mortise bolt body.
11. If your emergency egress trim is the screw on variety,
repeat step 9 on the exterior side of the door.
If your trim is the optional tap in variety, use a rub-
ber mallet to gently tap the emergency egress collar
into the through hole on the exterior side of the door.
Hand screw the emergency egress access button
into the collar - do not over tighten.
Door Jamb
12. Carefully measure the jamb to determine the exact
location that the latch strike and lock bolt land when
the door is fully closed. Mark the locations. Using the
strike plate as a template, outline the shape and begin
to mortise the door jamb to accept the strike.
Mortise the dust box cavities as shown here. If
using a full lip latch strike, the dust box will be smaller;
measure carefully and install.
After installation, if the latch does not fully engage
with the strike, loosen the screws and adjust slightly.
