B-LINE BB33L – Frequently Asked Questions

1) What is the B-Line BB33L box support actually used for?
The BB33L is a long leg box support bracket that fastens an electrical box to finished drywall. It is the part you reach for when a box has to land where there is no stud to screw into, such as a cut-in for an added receptacle or switch after the wall is closed up.
2) Is the B-Line BB33L box support UL listed for electrical work?
Yes. The BB33L carries a UL/CUL listing, which is what an inspector or a facility spec will look for on a box support going into a commercial or institutional job.
3) Can I use the BB33L to mount a box to a stud instead of to drywall?
No, that is not what this bracket is for. The BB33L supports a box in finished drywall. If you are framing and have a stud or a joist to land on, use a box with integral mounting ears or a bar hanger instead and keep the BB33L for retrofit cut-ins.
4) What is the exact part number and manufacturer for this long leg box support?
It is model BB33L from the Eaton B-Line series of box support fasteners. Order by BB33L; that is the manufacturer part number.
5) How much does one B-Line BB33L box support weigh, and does it need to carry the box on its own?
Each BB33L weighs 0.049 lb, with 1 inch height, 1 inch width, and 1 inch length depth plus the 2.5 inch Length A leg. It is a light sheet bracket, so it is sold and used in pairs, one on each side of the box, to carry the box in the drywall.
6) Is the BB33L box support galvanized or bare steel?
Pre-galvanized. That coating is why it is used behind drywall in normal dry interior walls without a separate finish being applied.
