Composite Jamb Routing and Installation Tips
1.
Fastener and shim spacing should be set
at 16" or less.
2.
To fasten the jamb parts to the stud wall,
pre-drill and countersink for at least 2"
fastening screws under the area covered
by the weatherstrip.
3.
Make sure all countersunk holes are deep
enough to accommodate the screw
heads, and avoid over-torquing when
driving. The composite jamb material has
10 times the holding power of wood and
for that reason we recommend that a
light coat of screw lube or wax be
applied to all hinge and assembly screws
prior to driving.
4.
Indicate shims to fasten through. Make
sure to locate one set of shims under
each hinge.
5.
At least one screw per hinge should be
long enough to run through shim into
the supporting wall stud.
6.
For radius systems, make especially sure
that the unit is sitting flat on a level floor
and shim the head area with the door in
place to insure that the factory radius is
maintained and that there is an even
reveal around the door. An uneven floor
may make it difficult to maintain the
radius without trimming one jamb leg or
shimming the sill.
7.
Finish nails are best driven with a
compressed air nail gun. Due to the
density of the material, it may be
necessary to use slightly more air
pressure than one would use for
softwood. The pressure required should
be similar to that needed for hard, dense
woods such as oak. As a cautionary note,
due to the nail holding power of the
composite materials, it may be difficult to
extract a mis-fired nail. Should that
happen to occur, consider cutting the nail
off and driving any remaining portion
beneath the surface.
8.
Although it is possible to prepare for a
hinge or strike plate with a chisel, we
strongly recommend that the strike prep
be done with a router, collett and jig. If
necessary, the corners can be easily
squared with a chisel. The images show
three examples of templates used with
1/2" bits and 5/8" collets for common
hinge and strike plate applications. The
few minutes it takes to fabricate the
jig out of 5/8" plywood or MDF will
be more than offset after just a
couple doors.
