Locksets

Cylindrical locksets are used most often. These locks take the standard 161 prep which is a 2 1/8" crossbore, 2 3/4" backset, and a 2 1/4" x 1 1/8" square corner door edge cut out. The standard strike plate with these locks is the 497 ANSI which is 4 7/8".

Mortise locks provide the highest level of security. The prep for this lock is an 8" x 1 1/4" edge cut out with holes drilled in the face of the door at locations depending on the different lock functions required. The lock body inserts into the edge prep so it is recessed into the door. The handles and cylinders (if required) are then installed through the door into the lock body.
