B-LINE BB40-08 – Frequently Asked Questions

1) What is the Eaton B-Line BB40-08 Uni-Mount bracket used for?
The BB40-08 is a Uni-Mount box support and cover plate mounting bracket for communication and low voltage work. It supports the box in the wall and gives you a mounting surface for the cover plate, in a single gang configuration.
2) Will the B-Line BB40-08 bracket work for a two-gang opening?
No. The BB40-08 is a single gang bracket only. For a two-gang or larger opening you need a multi-gang version of the Uni-Mount support, not this one.
3) How much does the BB40-08 bracket raise the device out from the box?
It gives a 0.5 inch raise. That is what brings a low voltage device or plate forward to sit flush when the box sits back behind drywall or a finished surface. If your finish thickness is more or less than a half inch, the raise won't land the plate flush.
4) Is the Eaton B-Line BB40-08 a UL listed part for low voltage installs?
Yes, the BB40-08 carries a UL/CUL listing, which covers it for both US and Canadian jobs where an inspector wants listed support hardware.
5) Can I use the BB40-08 support bracket on line voltage receptacle boxes?
It is catalogued by Eaton B-Line for communication and low voltage applications. Buying it for a standard power receptacle box is outside what the part is specified for, so match it to data, coax, telecom and similar low voltage openings.
6) What part number do I order for the single gang half inch raise B-Line Uni-Mount bracket?
Order Eaton B-Line model BB40-08. One model covers this configuration: single gang, 0.5 inch raise, pre-galvanized.
7) What finish is on the B-Line BB40-08, and is it OK for damp locations?
The bracket is pre-galvanized steel. That coating suits dry interior wall cavities and general rough-in work; it is not a hot-dip or stainless finish, so treat it as an indoor part.
