Measuring the Latch Line & Center Lines:
1.
Measure the center line of the door. This is shown
as "Y" on the diagram to the left.
2.
Measure the distance from the door latch to the
edge of the door frame. This is the door latch line.
This is shown as "X" on the diagrams below.

Mounting the Template:
1.
Measure distance "X" from the side of the door frame, and distance "Y" from the top of the
door frame. Use a pencil to mark the exact spot where the two lines intersect.
2.
Carefully peel off the short, thin tab in the center of the stick-on template. When placed
against the frame, this opening in the template will easily line up with the X-Y mark.
3.
Peel the template from the backing, and carefully apply it to the door frame.

Note:
The electric strike must be installed in such a way and in such a location as not to impair
the operation of any emergency exit and panic-mounted hardware on the door.
