American Tool Bi-Metal Door Lock Installation Kit #17104. This American Tool door lock installation kit features a self-centering jig that will eliminate the fear factor of drilling the holes incorrectly. The self-centering jig provides perfect hole alignment for face and edge holes. Plus it allows for easy enlargement of smaller existing holes. The fold over tabs adjust for 1-3/8" and 1-3/4" thick doors. The mounting holes secure the jig and match the latch plate holes. A deep 2-1/8" bi-metal hole saw bores completely through 1-3/4" doors. The 1" bi-metal hole saw cuts a straight, clean hole where the face plate goes.
