OWNERS MANUAL
WHEN USING POWER TOOLS
ALWAYS WEAR
EYE AND EAR PROTECTION!!

THINK
SAFETY!!
WHEN USING POWER TOOLS
ALWAYS WEAR
EYE PROTECTION!!
Before attempting any installation know
how to safely use the power tools involved.
Be sure all bits and cutters are sharp and
in good condition and all power tools and
extension cords are in good working order
and properly grounded. AND MOST
IMPORTANTLY, BE SURE TO WEAR,
EYE AND EAR PROTECTION.

To adjust for 2-3/8” or 2-3/4”
backset locks, just rotate the
backset knob both on the top
and bottom.
Using the supplied allen
wrench, install the proper
size break out plate/hole saw
guide. Two 1-1/2” and
two 2-1/8” guides are
supplied. For wood door use
mount with the washers on
top of the break out plate.
For steel door use, mount
with the washers under the
break out plate. Remove the
multi-spur guide on opposite
side and replace with
another guide as shown in
picture.
There are three drill guide
bushings supplied with the
HIT-44 for use when drilling
the edge bore, they are
held in with a clip. Choose
from a 7/8”, 1” or the brass
guide for use with a multi-
spur bit, they just snap in.
HIT-44 ADJUSTMENTS

ADJUSTING THE LATCH HOLE
CENTERING FEATURE
The HIT-44 is unique in the fact that the latch or edge bore hole
can be adjusted to drill on center or offset. To check for
centering, just turn the main clamp knob until the right and left
hand jaws are flush with the cut out in the core. If they are both
flush the HIT-44 will drill a centered latch hole. To adjust
centering or set up for an offset hole see next page.

TO ADJUST CENTERING
The HIT-44 has a unique feature in the fact the centering can be adjusted.
This will allow you to drill a centered latch hole in the edge of the door or
one that is off centered. This is handy in case a door has an additional
skin or plywood added on for re-enforcement. By loosening the allen
screw holding the brass KNURLED knob and you can move one jaw
independent from the other. This will move the centering of the latch hole
by the amount you moved the jaw. Adjust the knob until you have the hole
where you want it. Tighten the allen screw and drill the latch hole. It is a
good idea to re-center your drill guide after use so a door won’t be
mis-drilled next time. To re-center, turn the large main clamp knob until the
clamp jaw on that side is flush with the core cut out . Loosen the brass
KNURLED knob on the opposite side and adjust that jaw until it is also
flush with the core cut out. Tighten the allen screw and the unit is now
centered.

Prior to clamping the
HIT-44 to the door, check to
make sure the backset
adjustment knobs
correspond to the lock you
are installing.A 180 degree
turn of the knob will change
the backset to 2-3/8” or 2-
3/4”
Clamp the HIT-44 to the
door with a light pressure,
just enough to hold it on the
door.
Now tighten the black
plastic cantilever knobs
until snug.
USING THE HIT-44

One final turn of the main
clamp knob will secure the
HIT-44 to the door.
When the cross bore has
been completed, drill the
edge bore. Snap in the
proper size bushing for the
job.
Drill the cross bore first
using the proper size multi-
spur bit and corresponding
break out plate on the op-
posite side. USE A LOW
RPM WHEN DRILLING
AND BACK OUT THE BIT
FROM TIME TO TIME TO
REMOVE CHIP BUILDUP.

We are using a 1 inch brad
point bit for drilling the edge
bore. Again use a low RPM
and back out the bit to help
remove chips.
Remove when completed.
Here we are using our
HIT-44LM3 latch marking
tool to mark the area for the
faceplate. There is a 1/16”
shim that is used to adjust
to a 1” or 1-1/8” face. With
the shims on the inside, this
will mark a 1-1/8” face.

The use of a combination
square will help to square
the marker to the door.
Mark for the faceplate.
Use a sharp box cutter to
deepen the vertical outline
left by the marking tool. If
you use a chisel for this
step you run the risk of
splitting out the side of the
door.

A chisel can be used to
deepen the top and bottom
of the outlined area. Once
everything has been
outlined, chisel out the latch
mortise.
Don’t forget to mark the
jamb for the strike plate.
Shown is our HIT-44SL8
strike locator.
Use one of our centering
drills to drill for the latch
screw. This will assure a
centered hole and will allow
you to drive in the screw
with out splitting the door.
Do not attempt to drive in a
screw without a pilot hole.

Install the lock per the
manufacturers instructions.
