5. Adjust Lock for Door Thickness (if necessary)
Lock is factory preset for 1-3/4" (44mm) doors unless specified. To adjust lock to door thickness if other than 1-3/4" (44mm):
1. Remove outside trim assembly from the lockbody assembly. The lever, rose, and spring housing will remove as one piece
from the lockbody (See Figure 4).
2. Rotate outside rose liner to adjust lock to fit door thickness, so distance (Dimension A) from inside surface of liner to
centerline of retractor is half the thickness of the door (See chart and Figure 5).
3. Reassemble outside trim assembly onto lockbody assembly.
