Model 1455-3 Door Lock
Installation Guide
4.0 Lock Cutting & Mounting
4.1 Lock Cutting Using Standard Handle Height
Refer to the figures on this page. When using the
standard handle height of 1050 mm no cutting below
the lockbox is necessary.
Make sure the 1455-3 lock, extensions and top
terminal shoot-bolt are in the open position (see note
below). Position the 1455-3 lock in the door lock-stile.
The bottom of the lock should be flush with the bottom
door edge. Position the top terminal shoot-bolt so that
it is flush with the top edge of the door. Position any
extension(s) between 1455-3 lock and top terminal
shoot-bolt. Mark the faceplates of extension(s) and/or
lock where they touch so that when connected the top
terminal shoot-bolt it will be flush with the door top
edge. Connections are made by mating saw-toothed
coupler with saw-toothed drive rod. Using a vise and
hacksaw, cut the 1455-3 lock to length (both faceplate
and saw-tooth drive rod).
The sliding cover on the faceplate plate will hide any
minor gap or cutting imperfection.
Remove lock, any extensions and top terminal shoot-
bolt from door lock stile.
Note: The top terminal shoot-bolt and extensions
should come in a “locked open” position. This is
to help in the cutting process. When all hardware
is fitted and mounted a simple movement of the
handle lever will “unlock” these pieces.
