APPENDIX C
Mortise Cylinder/Cam
The mortise cylinder and cam is field replaceable. The cylinder is retained by a knurl-nut and
bracket to ensure proper alignment and provide anti-rotational support. The nut is removable,
and may be loosened or tightened by using a flat-blade screwdriver.
Alternate Cylinders
Cylinders must be 1-1/8” [28.6mm] deep style for proper alignment with the mode selection
switch. The use of 1” [25.4mm] or 1-1/4” [31.8mm] cylinder is not recommended. Figure C-1
specifies the recommended dimensions. If a longer cylinder is used, a spacer ring must be
added for proper alignment.
