APPENDIX B: Surface-Mounting the Spectra
1. If screwholes of the proper width, depth, and
spacing don’t already exist in the mounting
surface, such holes will need to be drilled by an
experienced person taking all appropriate safety
precautions. The holes in the mounting plate can
be used as guides. (Make sure to get the proper
authorization to have this done!)
2. If you haven’t already done so, place the plate on
the mounting surface so that its middle groove is
lower than its “wings.” Align the holes in the plate
with the screwholes in the surface.
3. Screw your selected pair of screws through the
holes in the mounting plate, into the screwholes
in the surface. Make these screws tight enough that
the plate doesn’t move when you jiggle or bump it.
4. If you look at the bottom of the Spectra, you’ll see
that it has a recessed track with wraparound flanges
on either side. Slide the bottom of the Spectra
onto the plate along this track, so that the plate’s
elevated wings fit snugly into the flanges. The
Spectra will not lock into place, but if you slide
it all the way onto the plate, it will be very tightly
secured.
