For flush construction, the 1-1/8 inch extension cam with 11/32 inch offset lets the cam sit correctly behind a flush front, aligning with the frame for positive engagement. For overlay applications, the combined thickness of the front and frame cannot exceed the specified cylinder length, so selecting the proper cylinder keeps the tailpiece within working range of the strike. The lock provides a 90 degree cam turn, giving quarter-turn operation from locked to unlocked, which helps with quick, repeatable positioning during layout and adjustment.
