Step 4.
Measure the inside of the frame. Determine and mark the halfway point. From this point,
use a ruler to draw a line straight down so that it intersects the existing line.
Step 5.
Use a 7/8” (22.2mm) spade bit and a drill to make two partially overlapping holes about
0.6” (15mm) deep centered both above and below the center line. If needed, use the chisel
to make the hollow (aka “mortise”) more square.
• If you choose to use the strike box, you may need to chisel slightly deeper.
• If using a spade bit, do not drill at high speeds as this may tear out extra wood and damage the
door or doorframe.
Step 6.
Hold the strike plate over the mortise. Using a pencil, mark a line around the edges of plate
to use as a guide. After marking at the straight edges of the plate, remove the plate.
Step 7.
Chisel about 1.5mm deep or until strike plate sits flush with door frame. If you choose to
use the strike box, you may need to chisel slightly deeper.
During chiseling, stop periodically and check to see if the strike plate sits flush in the doorframe
over the strike box. If not, chisel a little more and check again. Be careful not to chisel too deep;
otherwise, the lock may not function correctly after installation.
Step 8.
Position the strike and strike box, then use a pencil to mark the center points
of the screw openings in the strike plate. Set the strike and strike box aside
and drill two small holes at each center point.
Step 9.
Position the strike and strike box. Add the two remaining Wood Screws and
use a screwdriver (not included) to secure them.
