WHEN PREPPING DOORS, BE SURE TO ACCOUNT FOR THE LEFT HAND INSTALLATION BY FLIPPING BOTH THE DEADBOLT AND THE TEMPLATE UPSIDE DOWN.
Strike and deadbolt face-plate are 2 1/4" long x 1" wide:
Because these three holes are off center:
Be sure to flip deadbolt AND template upside-down For Left-Handed installation
For Hollow Wood & Metal Doors simply drill the three 7/16" holes through to the other side of the door. There's no need for the 1 5/8" hole on the inside of door unless you add the L.E.D. option.
