Major HIT-66-280
Drill Guide
Installation Template for the Schlage AD Mortise Locks
Major Manufacturing’s new HIT-66-280 tem- plate is designed to
quickly and accurately install or
retrofit the Schlage AD series
mortise locks. All required
holes are lined with hardened
drill bushings, the larger holes
for wire runs will also accept
hole saws. The angled hole
for the DPS is also templated
and is easy to drill. Plates are
machined from aluminum and
hard anodized. This template
requires the HIT-66 clamp
system that includes the HIT-
4509 mortise alignment plate
(sold separately). Template set
includes both inside and outside templates guides and DPS
wire run guide.
Using the HIT-66
1. With both clamps opened
equally, install both inside and
outside templates to the HIT-66
clamp as shown. Do not tighten
the 10-32 screws at this time.
When all screws have been
loosely installed, then it is ok
to tighten. With a 5/32” Allen
wrench, install the DPS drill template to the top of the clamp.
2. Install the alignment guide to
either side of the template set.
This is used to align the template
with the mortise pocket.
