B-Line Eaton series strut fittings and accessories, 4" Height, 9" Length, 1.62" Width, 1.93lbs, Steel, Bracket, Uniform load capacity 1450 Lbs, Electr

The bracket is punched with two holes, one of which is 9/16 inch diameter. A 9/16 inch hole takes a 1/2 inch bolt with normal clearance, which is the standard strut hardware size, so 1/2-13 strut nuts and bolts are what you'd order with it.

The finish is electro-plated zinc on a steel body. That's a light-duty corrosion finish meant for dry indoor service, mechanical rooms, and concealed spaces. For exterior work, a wash-down area, or a corrosive process environment, step up to hot-dip galvanized or stainless strut fittings instead.

It measures 4 inches high, 9 inches long, and 1.62 inches wide, and weighs 1.93 lbs. The 1.62 inch width is the giveaway that it's sized to sit on standard 1-5/8 inch strut channel.

Certifications are marked Not Applicable for the B187ZN. It's a mechanical support fitting, not an electrical device, so it doesn't carry a device listing. Where a job spec calls for listed supports, that requirement normally attaches to the raceway or hanger system rather than to a strut bracket.

It's a steel strut bracket from Eaton's B-Line strut fittings and accessories line, used to tie strut channel to a wall, deck, or another run of channel when you're building conduit racks, pipe supports, or equipment frames. Two punched holes let it bolt through with standard channel hardware, and at 1,450 lbs uniform load it handles typical electrical and mechanical support work.
