A
LIGNING THE CHASSIS AND TRIM
Establish a schedule to inspect locks, doors, and door hardware for
proper alignment and operation. Occasionally a lock chassis and/or rose
trim may become loose and require tightening.
To retighten a loose or misaligned chassis or rose trim:
1. Remove the following components:
■
levers ( page 3–2 or page 3–3 )
■
inside rose and rose liner ( page 3–5 ).
2. Align the chassis with the latch. Make sure that the latch tabs engage
the chassis frame and the latch tailpiece engages the retractor, as
shown in Figure 3.11 . The outside rose and liner should also be flush
with the door.
3. If the chassis is not aligned with the latch, or the outside rose is not
flush with door, perform these steps:
a. Slide the chassis assembly out of the door.
b. Retract the rose locking pin and adjust the outside rose and liner
assembly as necessary, as shown in Figure 3.12 .
c. Release the rose locking pin when it is lined up with an indent in the
liner and the posts on the liner match up with the chassis screws.
The pin should lock into the rose liner.
