Orbit FA-SSB-UMAB – Frequently Asked Questions
1) How does the Orbit FA-SSB-UMAB handle different drywall or ceiling finish thicknesses?
Depth adjustment is built into the assembly. The box-and-support configuration lets the installer set box depth and position relative to the finished wall or ceiling surface, so you can set it flush at rough-in and trim it to the actual finish thickness later instead of shimming or swapping boxes.
2) Does the Orbit FA-SSB-UMAB come assembled or do I have to build it on site?
It ships preassembled from the factory as a complete box and support assembly, so the box is already married to its support and there is nothing to bolt together in the field.
3) Is the Orbit FA-SSB-UMAB steel box strong enough to survive drywall hangers and rough-in abuse?
It is fabricated from 16 gauge sheet steel, a heavier wall than typical light-gauge boxes, chosen so the support structure stays rigid and does not deform during installation and drywall work. For a property manager or facility standardizing rough-in hardware, that is the trade-off you are buying over a thinner plated box.
4) What is the exact Orbit part number for the adjustable support box assembly?
Order it as Orbit FA-SSB-UMAB. That is the manufacturer part number for the 4 x 4 x 3-1/2 inch, 46 cubic inch sheet steel adjustable box and support assembly, and it is the only configuration in the model.
5) Can the Orbit FA-SSB-UMAB be used for both new construction and existing walls?
It is built for new construction rough-in, where you set the support before the wall or ceiling is closed in. In a finished wall there is no way to mount the support structure without opening the surface, so for retrofit work you want an old-work box with retainer ears instead.
6) Why is the Orbit FA-SSB-UMAB box red?
The red housing is for identification. On a jobsite where several box types are in the walls at once, the red finish lets the inspector or foreman spot these assemblies during rough-in inspection without pulling a tape or a print.
