Model 1455-3 Door Lock
Installation Guide
4.2 Lock Cutting using Lowered Handle Height
Refer to the figures on this and the preceding page.
When lowering the handle height cutting below the
lockbox is necessary with the addition of a bottom
shoot-bolt terminal.
The lowest the handle may be
located is 748 mm (37-5/46”) from the door bottom
edge.
Make sure the 1455-3 lock, extensions, top and
bottom terminal shoot-bolts are in the open position
(see note below). Position the 1455-3 lock in the door
lock-stile. Because the handle height is being lowered
the bottom of the lock will not be flush with the bottom
door edge. Position the bottom terminal shoot-bolt
flush with door bottom edge. Mark the 1455-3 lock
faceplate where it touches the bottom terminal shoot-
bolt faceplate so that when connected the lower
terminal shoot-bolt will be flush with the door bottom
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).
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 & bottom
terminal shoot-bolts.
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.
