B-LINE BB-18 – Frequently Asked Questions
1) Will the B-Line BB-18 box support work in both 16-inch and 12-inch on-center stud bays?
Yes. The BB-18 is an 18 inch bar with a break-away feature so it can be snapped down for either 12 inch or 16 inch box mounting between studs. You cut nothing, just break it at the score point for the narrower bay.
2) Is the BB-18 bar hanger UL listed for electrical box support?
The B-Line BB-18 support is UL/CUL listed, which covers it for use on both sides of the border for inspected electrical work.
3) What is the BB-18 bar hanger actually for, floor boxes or wall boxes?
Eaton B-Line lists the BB-18 as a floor-mount box support, mounted to wall studs or floor framing to carry an electrical box between members. It's the bar itself, not the box.
4) What part number do I order for the B-Line 18 inch break-away box support?
Order Eaton B-Line model BB-18. That is the manufacturer part number for the 18 inch pre-galvanized break-away box support.
5) Does the BB-18 come with the electrical box or any screws?
No. The BB-18 is the support bar only. You supply the box and the fasteners to attach it to the studs.
6) Can the B-Line BB-18 be used in damp or unfinished areas, or is it plain steel?
It's pre-galvanized steel, so it has a zinc coating already on it before forming. That suits typical interior framing and unfinished spaces; it is not a stainless or hot-dip part for corrosive or exterior exposure.
