B-LINE BB45-08 – Frequently Asked Questions

1) What is the Eaton B-Line BB45-08 Uni-Mount bracket used for?
The BB45-08 is a Uni-Mount box support and cover plate mounting bracket in the Eaton B-Line series, made for double gang openings on communication and low voltage work. It supports the box and gives the cover plate a solid mounting point, with a 0.5 inch raise built in so the plate sits proud of the finished wall surface.
2) Will the B-Line BB45-08 bracket work on a single gang opening?
No. The BB45-08 is a double gang bracket, so it is sized for a two gang box and cover plate. For a single gang opening you need the single gang version of the Uni-Mount bracket instead.
3) What does the 0.5 inch raise on the B-Line BB45-08 do for me on the job?
The 0.5 inch raise sets the mounting plane forward half an inch, which takes up the gap when the box sits recessed behind thicker wall finish such as added drywall, tile, or panel. It brings the cover plate flush with the finished surface without shimming the box.
4) Is the B-Line BB45-08 bracket corrosion resistant enough for damp interior locations?
The bracket is pre-galvanized steel, which gives a zinc coating applied before fabrication. That is the standard protection for interior and concealed dry or damp work; it is not intended as an outdoor or corrosive-environment finish.
