B-LINE BB70 – Frequently Asked Questions

1) What metal stud widths does the B-Line BB70 box support bracket fit?
The Eaton B-Line BB70 box support bracket is made for metal studs from 2.5 to 4 inches. That covers the common 2-1/2 inch, 3-5/8 inch and 4 inch drywall studs used in commercial partitions. On wood studs or on stud sizes outside that range, it is not the right bracket.
2) Is the BB70 box support bracket UL listed for electrical work?
Yes, the BB70 carries a UL/CUL listing, so it satisfies inspectors on both US and Canadian jobs where a listed box support is required.
3) Why use a box support bracket instead of screwing the device box straight to the stud?
Screwing a box to one stud flange leaves it free to rack when the drywall goes on or when devices get pushed and pulled. The BB70 bracket spans the stud cavity and its interlocking design adds rigidity, which holds the box square to the finished wall face. That matters most on multi-gang boxes and on walls that see heavy device traffic.
4) What are the dimensions of the B-Line BB70 bracket?
The BB70 is listed at 1 inch height, 1 inch length and 1 inch width, with a stud span rating of 2.5 to 4 inches. Use the stud size figure, not the 1 inch body dimensions, when you are checking whether it suits your partition.
5) Do I order the BB70 in more than one version?
No. The B-Line BB70 is a single catalog number with no finish or size options to specify, so ordering is just quantity. One bracket per box location is the usual takeoff.
