B-LINE BB9 – Frequently Asked Questions

1) Will the B-Line BB9 box support fastener work on metal studs?
Yes. The Eaton B-Line BB9 is a box to stud fastener made to attach electrical boxes to most metal studs. It is not a wood stud fastener, so if you are framing in lumber you want a box with a nail-on bracket or a wood screw mount instead.
2) How does the BB9 set the box depth relative to the drywall?
It mounts flush to the back of the drywall, so the box face lands against the back side of the board rather than being set by eye. That is what keeps the device ring at the right depth on a standard single-layer wall without shimming each box.
3) Is the Eaton B-Line BB9 box support fastener UL listed for electrical work?
The BB9 carries a UL/CUL listing, which is what an inspector or a facility spec will usually ask for on box support hardware in commercial and institutional work.
4) Should I use a box support fastener like the BB9 or a bar hanger between studs?
Use the BB9 when the box lands on or beside a stud and you just need it fixed to that stud at the right depth behind the drywall. A bar hanger is the right call when the box has to sit mid-bay, away from any stud, because it spans between two studs and carries the box in open space. The BB9 is a stud-attached fastener, not a spanning support.
5) Does the BB9 come with the electrical box, or do I buy the box separately?
The BB9 is the fastener only. It is the hardware that ties an electrical box to the metal stud and holds it flush to the back of the drywall; the box, device ring and cover are all ordered separately.
6) What part number do I order for the B-Line box to stud fastener?
Order Eaton B-Line model BB9. That is the single model for this box support fastener, so there are no size or finish choices to specify.
