The strike will hold the bolt in place keeping the door locked until the bolt is retracted using a key or thumb turn. Using a router attachment remove the wood between the pencil lines drawn on the door edge to create a mortise for the faceplate.

The strike is installed on the door frame and contains a hole that catches the latch or bolt that extends from the lock. Close the door and look for where the lock bolt or latch bolt contacts the door jamb. Select a lock with the same setback. Mark the precise centre top to bottom of the bolt onto the inside edge of the jamb using a pencil.
