Yes, the BBF18 carries a UL/CUL listing, so it covers both US and Canadian jobs. That matters on inspected commercial and institutional work where the inspector wants listed support hardware behind the box, not a field-fabricated bracket.

The BBF18 is an 18 inch floorstand, so it sets the box at roughly standard receptacle height off the deck. If your drawing calls out a different mounting height for the device, this is not the stand to use, look for the floorstand length that matches the called-out height.

The BBF18 is an 18 inch floorstand box support, used to hold an electrical box off the floor at a set height during rough-in rather than hanging it between studs. It mounts to the floor and supports the box from below, which is how you set outlet or device boxes in open framing or where there is no stud in the right place.

It is pre-galvanized steel, which is the standard finish for concealed rough-in support inside dry framed walls. It is not described as hot-dip or stainless, so treat it as an interior, dry-location support rather than an exterior or wet-location part.

Use a floorstand like the BBF18 when the box height is set from the floor and there is no convenient stud pair to span, or when you want the box located independently of framing. A bar hanger is the better choice when you are setting the box between two studs at a fixed spacing and want the box tied into the framing. The BBF18 is specifically a floor-mount support.

Each BBF18 weighs 1.103 lb. It is ordered by the single model number BBF18, so quantity is a straight count against your box count on the rough-in.
