Deadlock Functions

Double cylinder deadbolts have a key on both sides while single cylinder deadbolts have a key on one side and a thumbturn on the other side. 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.
