Use the HIT-45
clamp system to
route faceplate
openings in
wood doors.
PREPAIRE YOUR HIT-45 CLAMP
Using your left hand (if you are right handed)
squeeze together the spring loaded jaws of
the HIT-45 clamp to release the spring
pressure.
Loosen the black plastic knob until you can ro-
tate the vise block 180 degrees, this will allow it
to rotate freely. Repeat this procedure with the
other end of the clamp.
The clamp heads will now spin left to right.
This will allow the clamp to align to the door
bevel.

Attach the bevel blocks both top and bottom
on the inside of the HIT-45 clamp with the
supplied 10-32 x 1/2” flat head socket
screws. These blocks pick up the door bevel.
THE BLOCKS MUST BE REMOVED WHEN
DRILLING THE LOCK FUNCTION HOLES
LATER OR IF USING THIS CLAMP ON
ALUMUNUM DOORS! FAILURE TO
REMOVE THEM WILL CAUSE THE LOCK
BACKSET TO BE MIS-DRILLED.
Install the HIT-45AR5 template using the
supplied 10-32 x 1/2” long flat head socket
screws. Using a 5/8” router template guide
and a 1/2” router bit, this template will route a
1-1/4” wide x 8” tall faceplate.
Thread the pointer in the center hole of the
five tapped holes as shown.

SET UP YOUR ROUTER
Set up your router by installing a 5/8” outside
diameter template guide and a 1/2” diameter router bit.
Start by extending the router bit 1-1/16” past the base
plate and test. This will be very close to the proper
depth. It is best to test on a scrap wood block prior to
installation. By measuring the distance from the router
base to the end of the router bit, this set up can now be
duplicated at any time.
To center the template we must find the center of
the lock mortise. Using a combination square,
make a pencil line at the top and bottom of the
mortise as shown.
Pencil mark at top of lock mortise, mark the bottom
the same way.

Measure the distance between the top and
bottom of the mortise and divide by two.
Make a mark at this point, this will be the
center of the mortise pocket and the center of
the mortise faceplate.
Hold the HIT-45 to the door with the locating
pointer pointing to the center line, allow the
bevel blocks to conform the door bevel and
tighten clamps. Double check the pointer is
located to center and remove the pointer.
Failure to remove the pointer will
result in it being struck by the router bit.

ROUTE THE OPENING
With the router bit adjusted to the proper depth
and the HIT-45 clamp and template properly
located, place the router in the template guide
with the bit extending into the mortise pocket.
Using both hands for control, turn on the router
and route the opening in a clockwise direction.
When completed, let the router come to a
complete stop before removing it from the
template. FAILURE TO DO SO MAY CAUSE
DAMAGE TO YOUR TEMPLATE, THE DOOR
OR INJURY TO YOURSELF. Check the work
area and make a clean up pass if needed.
When completed, remove the clamp from the
door and square the corners with a chisel.
Shown is the use of a corner squaring chisel.
Use a standard chisel to finish removing the
round corners and final cleanup.

Finished faceplate ready for the mortise lock
installation.
That’s all there is to it!
If using your HIT-45 clamp for drilling the
function holes, don’t forget to
remove the bevel blocks and turn the clamp
blocks back to the locked
position.

Using the
HIT-45 clamping
system to
install mortise
locks.
The HIT-45 modular clamping system utilizes a unique design that is both
self aligning and self centering on all types of doors. The HIT-45 uses two
internal locating studs that always assures that the backset is located from
the center of the door edge regardless of the door type of the door edge
encountered (flat, beveled or radius door edge). With the appropriate
templates installed, the HIT-45 can be used to route lock openings in
aluminum frames or install mortise locks on wood and hollow metal doors.
To setup your job simply attach the appropriate templates to the HIT-45
modular clamp and tighten the assembly to the door. Remember,
clamping pressure is always positive and therefore moderate clamping
torque applied to the clamping knobs is all that is needed.
This is the HIT-45 clamp that will be used to install a
mortise lock. It can be used to install a variety of
hardware using interchangeable templates.
There is a backset stud located in the center of the top
and bottom clamp. It will set the correct backset
calculated from the center of the door regardless of door
bevel.
NOTE: IF YOU HAVE USED THIS CLAMP TO ROUTE
THE FACEPLATE—BE SURE TO REMOVE THE
BEVEL BLOCKS, FAILURE TO DO SO WILL RESULT
IN A MIS-DRILLED DOOR.
When attaching the mortise lock template to the clamp,
be sure the center hole of the template is fastened to the
center hole of the clamp.
