3. Measure and Mark
A. Mortising for Lock Plates: The lock/bolt hole will be your mark unless you choose to drill the hole later. Up and
down positioning accuracy for the lock plates is not as critical as it is for the hinges.
B. Mortising for Hinges:
CAUTION: With a sharp pencil or knife mark hinge center-lines across door or jamb with a square. This is important
for this system to produce the desired result.
With 2 small nails, lightly attach the door spacer shim to the top edge of the door. Now, with a tape measure
hooked onto the spacer shim, make accurate marks where you want the hinge center lines to be (See Fig. 3A).
Keep note of these measurements in the event of mortising for hinges on a matching jamb.
For replacing a door in an existing jamb with hinges already mounted, you must first make an accurate mark at the
center of each hinge. Then take a measurement from the top of the jamb door opening (See Fig. 3B) down to each
hinge center line. With the door spacer shim in position on the top of the door, transfer the jamb hinge center line
measurements directly to the door.
CAUTION: Prior to replacing a door in an existing jamb, check for squareness and level of the jamb hinge section
and the jamb header. Fit the new door accordingly. Then begin set-up to mortise for hinges according to the prior
instructions.

4. Position and Secure holding clamp to the door. For 1 3/8 inch doors, the adaptor pads must be in the active
"down" position (See Fig. 4). For 1 3/4 inch doors, the adaptor pads must be in the inactive “up” position.
A) Mortising for Lock Plates:
With proper template attached, position the clamp so the centering arrows are in line with the latch hole or a mark
if the latch hole is not drilled yet. Normally, the hole is present prior to mortising for the lock plate. By tightening
the wing nuts, secure clamp to door (only finger tighten to avoid marking the door). Clamp may be damaged if a
wrench is used and accurate centering of the clamp may be affected.
B) Mortising for Hinges:
When mortising for hinges, more accurate positioning is required than for lock plates. Although centering arrows
are indicated on the hinge templates, a more accurate positioning device is provided. This device will give you the
exact accuracy of your layout marks and lines.
After selecting and securing the proper hinge template, insert the positioning device into the hinge template
window. Now, position the entire clamp assembly on to the door and slide it up or down until the mark lines up
with the points in the positioning device (See Fig. 5).
Secure holding clamp to the door by tightening the wing nuts.
