B-Line Eaton series strut fittings and accessories, For support pipe on top or hanging support bracket, 1577 Lb load cap, Stainless steel, Light duty

The B3066-0 bracket is rated at 1577 lbs load capacity. It is classed as a light duty welded bracket, so that figure is the bracket's own rating and your anchors, strut, and structure have to be sized to match it, not the other way round.

Dimensions are 18 in height, 15.5 in width, and 12 in length/depth. Work from those three numbers when you check clearance between the mounting surface and the pipe centerline, plus whatever the clamp or strut adds on top.

Both. The B3066-0 is made for supporting pipe on top or as a hanging support bracket, so it works pipe-up off a wall or column and inverted as a drop hanger.

Plain finish, meaning no plating or paint. For interior dry electrical and mechanical spaces that is normal practice; for damp, exterior, or washdown areas specify a galvanized or stainless version of the bracket instead, because a plain finish will surface rust.

It is a welded bracket, so the angle and leg lengths are fixed as manufactured. That gives you a rigid one-piece part with nothing to loosen under vibration, but no field adjustment. If you need to tune the projection or height on site, build the support from strut channel and bolt-on fittings instead of a welded bracket.

No certification applies to the B3066-0; the certifications attribute reads Not Applicable. If your drawings call for a listed or labeled support assembly, the listing usually attaches to the hanger or seismic assembly as a system rather than to an individual welded bracket, so check what the spec section is actually asking for before you substitute.

It weighs 15.77 lb. At 18 in tall and 15.5 in wide that is a one-man lift but awkward overhead on a ladder, so plan on temporary support or a second set of hands when you set it before bolting off.
