4. Using the pilot hole, drill a 1” (25.4mm) diameter hole for the latchbolt into the edge of the
door. Make sure the latchbolt hole is level and perpendicular to the 2 1/8” (54mm) diameter
hole.
5. Mortise the edge of the door 1 1/8” x 2 1/4” x 5/32” (29mm x 57mm x 4mm) for the latch front.
For all doors:
1. Drill four 11/32” (8.7mm) diameter holes straight through the door.
2. Drill a 1/8” (3mm) diameter pilot hole straight through the door where you marked for the
centerline of the 1” (25.4mm) diameter hole for the system cable.
3. Using the pilot hole, drill the 1” (25.4mm) diameter hole for the system cable.
Note: Remove any burrs from the inside and outside edges of the 1” (25.4 mm) diameter
hole to prevent cutting of the system cable.
Optional Drill Jig:
An optional Drill Jig, Part Number 404044, is
available to ensure accurate locating and
drilling of the four 11/32” (8.7mm) diameter
mounting holes, and the 1” (25.4mm) diam-
eter system cable hole.
1. For the best results, align the jig to the
door with a combination square and
clamp to the door before drilling. Refer to
Figure 6.
