B-LINE BB4-23 – Frequently Asked Questions

1) Will the B-Line BB4-23 box support bracket work on 2-1/2 inch metal studs, or is it only for 3-5/8?
Both. The BB4-23 box support bracket is made for metal stud sizes of 3.63 inch and 2.5 inch, so it covers the two stud widths you see most in commercial partition framing. If your wall is framed in something outside those two widths, this is not the bracket for that opening.
2) Is the B-Line BB4-23 electrical box bracket UL listed for a hospital or school job?
The BB4-23 box support bracket is UL/CUL listed, which is what a spec writer on an institutional job is usually looking for on box support hardware. The CUL half means it is recognized for Canadian installations as well.
3) What finish is the B-Line BB4-23 box support bracket, and can it go in a damp location?
Pre-galvanized steel. The zinc coating is applied to the sheet before the bracket is formed, so it carries corrosion protection on the flat faces without a post-fabrication dip. That suits indoor and protected applications inside a stud wall, which is where box support brackets live anyway.
4) Does the B-Line BB4-23 come with screws to fasten it to the stud?
Fastening hardware is a separate line item. The BB4-23 is the bracket alone, and you secure it to the metal stud with the fastener appropriate to your stud gauge before hanging the box on it. Plan on framing screws in your material takeoff.
5) What is the actual part number to order this Eaton B-Line box support bracket?
Order it as B-Line BB4-23. That is the manufacturer part number, from Eaton's B-Line box support fastener line, and it is the identifier a distributor will cross to.
