Step 4. Strike Plate Installation
1) Using the template, locate the center horizontal
line for the deadbolt hole, which lines up with the
center of the 2-1/8˝ hole, and draw a horizontal line
on the door frame to mark where you will make the
deadbolt mortise hole.
2) Measure half the thickness of the door. Now,
measure that distance from where the door stops
at the frame when the door is closed toward the
door jamb and mark a straight, vertical line the
length of the door strike plate. Draw a horizontal
line from the mark you made in Step 1 toward the
vertical line. Where both lines cross, make a 1˝ (25
mm) diameter hole, 1/2˝ (13 mm) in depth.
3) Align the holes of the strike plate with the vertical
line. Trace the outline of the strike plate and
mortise with a 1/16˝ (1.6 mm) indentation. Attach
the strike plate with the 2 screws provided.
