B-LINE BB74 – Frequently Asked Questions

1) What stud widths does the B-Line BB74 box support bracket fit?
The BB74 is sized for 4 inch, 3-1/2 inch and 2-1/2 inch studs, so it covers the common metal stud depths used in commercial partitions as well as 4 inch framing. One part number handles all three, which is why it gets specified as a standard on rough-in carts.
2) Is the B-Line BB74 bracket UL listed for electrical rough-in?
Yes, the BB74 box support bracket carries a UL/cUL listing, which covers it for inspected work in both US and Canadian jurisdictions.
3) What does a double sided box support bracket do that a single bracket doesn't?
A double sided bracket like the Eaton B-Line BB74 supports boxes mounted on both faces of the stud, so you can hang back-to-back or offset devices from one piece of hardware instead of setting two separate supports. If you only ever mount on one face of the stud, a single-sided bar is the simpler pick.
4) What part number do I order for the Eaton B-Line double sided box support?
Order it as B-Line BB74. It is part of Eaton's B-Line Ruff-IN line of box support fasteners, and BB74 is the only model designation on the double sided bracket.
5) Will a pre-galvanized box bracket hold up in a damp or unheated space?
The BB74 has a pre-galvanized finish, which is the standard corrosion protection for concealed rough-in inside walls and ceilings, including unheated and humid interior spaces. It is not a hot-dip or stainless part, so for direct exposure to weather or a corrosive process environment you would want a heavier-coated support.
