Furniture mounting
Furniture mount the MSW using the optional MBU 123
VersaTools under-desk mounting kit (part #70-212-01) as follows:
1. If necessary, remove the feet from the bottom of the MSW.
2. Attach the mounting brackets to the MSW with the
provided machine screws (figure 2-3).

3. Hold the MSW with the attached brackets against the
underside of the table or other furniture. Mark the location
of the screw holes of the bracket on the mounting surface.
4. Drill four 3/32" (2 mm) diameter pilot holes, 1/4"
(6.3 mm) deep in the mounting surface at the marked
screw locations.
5. Insert #8 wood screws into the four pilot holes. Tighten
each screw into the mounting surface until just less than
1/4" of the screw head protrudes.
6. Align the mounting screws with the slots in the brackets
and place the MSW against the surface, fitting the screws
through the bracket slots.
7. Slide the switcher slightly forward or back, then tighten all
four screws to secure the MSW in place.
