B-Line Eaton series box support fasteners, Wall studs, 1" Height, 1" Length, 1" Width, 1.009lbs, 15" Floorstand, Floor-mount box support, Floor-mount

The BBF15 is a floor-mount box support, a 15 inch floorstand that sets an electrical box at a fixed height off the floor during rough-in. You anchor the base to the deck or subfloor and the box mounts to the upright, so the box position holds while the wall goes up around it. Finish is pre-galvanized steel.

Yes, the BBF15 carries a UL/CUL listing, which covers it for use in the US and Canada. That listing is what an inspector or an institutional spec typically asks for on box support hardware.

It is a 15 inch floorstand, so it is sized to bring a box up to a standard receptacle height range rather than a switch or thermostat height. If you need a different mounting height, you want a different floorstand length in the same B-Line family, not this one.

The BBF15 is pre-galvanized steel, which gives it a zinc coating for general indoor construction and concealed work. Pre-galvanized is a mill coating, not a hot-dip after fabrication, so for outdoor or wash-down exposure you would specify a hot-dip galvanized or stainless support instead.

Use the BBF15 floorstand when the box sits in a bay where you want the height set off the floor independent of the studs, or where there is no convenient stud pair at the right elevation. A bar hanger spanning stud to stud is the better pick when the box is at a height you can span horizontally and the studs are already in place. The BBF15 is the floor-mount answer, sized at 15 inches.

Order Eaton B-Line model BBF15. That is the manufacturer part number, and the 15 inch floorstand comes as a single configuration, so there is no finish or length option to specify with it.

About 1.009 lb each. Light enough to carry a bundle of them up a ladder, and it matters when you are pricing out freight on a few hundred for a multi-family rough-in.
