B-LINE BB4-4D – Frequently Asked Questions

1) What metal stud sizes does the B-Line BB4-4D box support bracket fit?
The BB4-4D box support bracket is made for metal studs in 4 inch, 3.63 inch, and 2.5 inch widths, so it covers the common drywall stud depths on a commercial partition. It mounts to the stud to carry an electrical box between framing members.
2) Is the B-Line BB4-4D box support UL listed for electrical work?
Yes, the BB4-4D carries a UL/CUL listing, which is what an inspector or institutional spec will look for on a box support in a commercial job.
3) Will a pre-galvanized steel box bracket hold up in an unconditioned or damp interior space?
The BB4-4D is steel with a pre-galvanized finish, which is the standard corrosion protection for concealed interior framing and plenum spaces. Pre-galvanized is not the same as hot-dip; for exterior or wet locations, a hot-dip galvanized or stainless support is the right call.
4) What does the double-set designation on the B-Line BB4-4D mean when I am ordering?
Double-set means the BB4-4D ships as a matched pair of brackets rather than a single piece, so one order number gives you both sides needed to support the box across the stud bay. Count your boxes, not your pieces, when you build the takeoff.
5) Is the B-Line BB4-4D bracket for wood framing or metal studs?
Metal studs. The BB4-4D is a wall stud box support sized to 2.5, 3.63, and 4 inch metal framing. On wood framing you want a nail-on box or a bar hanger intended for wood, not this bracket.
