LTKL 101 Electric Strike
Featured with a built-in door status sensor, the LTK101 is a fail-secure electric strike, but it is
field convertible from fail secure to fail safe. It can be mounted either right or left reversibly
on the doorjamb, providing remote release of a locked door.

3. Spacers are provided to ensure the final assembly of faceplate into the doorjamb. Add
one of spacers between the doorjamb and the mounting bracket when faceplate extends
beyond the doorjamb. When the faceplate sets inside the jamb, spacers must be added
between the mounting bracket and the tip bracket. Make sure the clearance hole in the
spacer aligns with the hole in the mounting bracket.
