Preparing the Routing Template
Extron offers a metal template, part #70-191-01, for the
HSA 822M and HSA 822. Extron recommends using this
template as a guide to cut the hole in the table where the HSA
will be installed.
The metal routing template is reusable. Do not discard
this template when the installation is complete. Save it
for future HSA 822M installations.
1 . Cut 1/2" x 4" strips of soft, finished lumber long enough to
span the distance between the desired installation location
on the table or other mounting surface and the edges of
the table (figure 2-2).

These strips raise the routing template above the mounting
surface to provide room for the router’s collar, protect the
mounting surface, and extend the reach of the routing
template so that it can be clamped to the edge of the
surface.
2 . Using four or more short wood screws, secure the
mounting template to the lumber strips.
CAUTION Do not allow the wood screws to protrude through
the bottom of the wooden strips. Protruding screws
will mar the table when the template is used.
Preparing the Table
The preferred and recommended method for preparing the
table is to use the appropriate Extron metal routing template
and a router.
Alternatively, you can use a paper cut-out template
(see appendix A, “Reference Information”) and a sabre saw or
keyhole saw, but this method is not recommended.
Prepare the table as follows:
CAUTION The opening in the table for the HSA 822M should
be cut only by licensed and bonded craftspeople.
Exercise care to prevent scarring or damaging the
furniture.
The routing templates for the various HSA models
are not interchangeable. If you use the wrong
template, you will cut an improperly-sized hole.
If you use a larger template than required, the cut
will result in gaps in the table surface on either side
of the enclosure.
The surfaces of the HSA enclosure have screws and
other protruding hardware that could damage fine
furniture. Do not rest the enclosure on unprotected
furniture.
The metal routing template is reusable. Do not discard
this template when the installation is complete. Save it
for future HSA 822M or HSA 822 installations.
The HSA 822M mounts in exactly the same size hole as
the HSA 822 and uses the same metal mounting
template.
1 . Locate the desired mounting location on the tabletop or
other installation surface. Mark the location.
CAUTION Ensure that only the wooden strips contact the
furniture. Failure to do so may mar the furniture.
2 . Place the mounting template assembly on the table,
centered on the mounting location. Angle the template for
the optimum positioning. If necessary, use a square to
ensure that the template is properly positioned. Extron is
not responsible for improperly-positioned HSA products.
3 . Once the template assembly is positioned properly, use
C-clamps to secure the assembly to the table for routing as
shown in figure 2-3 on the next page.
