FIGURE 3 illustrates a typical door/jamb where SOSS
Invisible Hinges will be mounted. Become familiar with
the terminology as it will be used throughout these
instructions.
Jamb Preparation (Refer to Figure 4)
1 Remove the guide pins from the router guide template.
2 Place the Router Guide Template on the hinge jamb
so the locator pins rest flush against the pull side
jamb face, and are on the inside of the intended
door swing. The spacer tab should be flush against
the head jamb, and positioned in line with the template
(i.e. tab positioned as packaged).
3 Once the desired position is established, the nails
can be tapped-in the door rabbet to secure the template
in place.

*The depth of the starter hole should be at least the values listed. Depths
exceeding those tabulated will not adversely affect hinge operation.
5 Being careful not to nick or gouge the template, drill
the starter hole for the router to the proper depth in
the center of the hinge outline of the template.
Routing the Hinge Outline
6 The chart in TABLE "B" lists the maximum depths to
which the hinge outlines should be routed. It is
advisable to check the depth of the cut you are
making prior to removing a significant amount of
wood. If desired, the required depth may be
obtained by making multiple router passes.

CAUTION: Do not exceed the listed depths when routing the hinge outline, as
binding of the hinges will occur.
7 Using whatever means of measurement best suited
to you, determine the location of the next hinge to be
mounted on the jamb. Mark or measure that distance
so as not to damage the door.
NOTE: Remember the distances you have
selected, as you will need to recall those
measurements when mounting the templates
on the door.
8 Remove the template from the jamb and move it
to the new location you have chosen, repeating
steps 2 through 7 for the number of hinges requiring
installation.
Door Preparation (Refer to Figure 3)
1 Prior to mounting the template on the door, make
certain that the door is properly oriented.
2 The clearance between the head jamb and the door
is set with the spacer tab. It should be positioned
one quarter turn so the template will hang from the
top of the door.
3 Place the Router Guide Template on the door so the
locator pins rest flush against the pull side face of
the door, and are on the inside of the desired direction
of the door swing.
4 Once the desired position is established, the nails
can be tapped in to secure the template in place.
5 Again, being careful not to nick or gouge the template,
drill the starter hole for the router to the depth
listed in TABLE "A" in the center of the hinge outline
of the template.

6 The chart in TABLE "B" lists the maximum depths
for which the hinge outlines should be routed. It is
advisable to check the depth of the cut you are
making, prior to removing a significant amount of
wood. If desired, the required depth may be cut in
multiple passes.
7 Recalling the measurements you made to determine
the hinge spacing on the jamb, use those identical
measurements to position the template for the next
hinge mortise on the door.
8 Remove the template from the top of the door and
move it to the new location repeating steps 3
through 7 for the number of hinges requiring installation.
At this point, the routing of the outline portions of the
hinge mortises is complete. The next step is to rout the
deep mortises.
Place the guide pins into their proper holes on the
template. The guide pins are threaded and must not be
hammered or otherwise forced into position. Care must
also be taken that the threaded guide pins are not
overtightened, as this may distort the templates.

Completion of the Jamb Mortises (Refer to Figure1)
1 Starting at the top hinge mortise, position the template
so the nails fit into the holes left in the jamb
from the previous rout. The locator pins should be
toward the inside of the door swing as before.
2 Once the proper position is reestablished, the nails
can be tapped in to secure the template in place.
3 To complete the routing of the hinge mortise, it will
be necessary to remove wood to the depth listed in
TABLE "C". It is recommended that multiple passes
be made, as opposed to removing all of the wood at
once.

CAUTION: Rout only the area between the guide pins. Do not remove any more
material from the circular outline or any outside the guide pins.
4 After the deep mortise has been routed, remove the
template.
5 Place a SOSS Invisible Hinge into the mortise you
have completed and inspect the following:
A Does the hinge fit "snugly" into the mortise.
B Does any portion of the hinge extend beyond
the rabbet of the jamb?
The body of the hinge should fit snugly into the mortise.
If the hinge body extends above the jamb after
the hinge has been pushed into the mortise as far as
possible, verify that the mortises have been routed
to the proper depths. Correct as required.
6 Position the template at the next location on the
jamb. Repeat steps 1 through 5 for the number of
hinges requiring installation.
Back to top
Completion of the Jamb Mortises (Refer to Figure1)
1 Position the template so the nails fit into the holes left
in the door from the previous rout. The locator pins
should be toward the inside of the door swing as
before.
2 Once the proper position is reestablished, the nails
can be tapped in to secure the template in place.
3 To complete the routing of the hinge mortise, it will be
necessary to remove wood from the door to the
depths listed in TABLE “C”. Again, it is
recommended that the wood be removed by making
multiple router passes.
4 After the deep mortise has been routed, remove the
template from the door and position it at the next
hinge location on the door.
5 Repeat steps 1 through 4 for each hinge requiring
installation.
Mounting the Door to the Jamb
Having completed the routing of the hinge mortises,
notice that the hinge mortise is not centered within the
thickness of the door. The "thin" section corresponds to
the inside surface of the door.
1 Place the SOSS Invisible Hinges into the mortises so
the hinge bodies straddle the thin section of the
door. Using the wood screws supplied with the
hinges, secure the hinges to the door.
2 The door can then be moved into a position where
the remaining hinge bodies can be placed into their
respective mortises in the jamb.
3 Secure the jamb side of the hinges with the remaining
wood screws.
4 Exercise the door to see that it opens and closes
freely throughout the required amount of opening.

a small diameter hole (approximately
1/8" diameter or less) should be drilled
at least 23/4" deep.
At the punch points marked with A,
drill the required size holes to the
depths listed below by hinge size.
At the punch point marked with B, drill
the required size hole according to the
following chart
