B-Line Eaton series beam clamps, Vertical adjustment provided in the clamp, Steel, Steel beam clamp, 1"-8 thread/rod size, Plain finish

Rated load capacity is 4300 lb. That is the clamp's rating only; the hanger rod, the beam, and any anchor in the run all have their own limits, and the assembly is only as strong as the weakest of them. For heavy trapeze runs of large conduit or pipe, the 1 inch rod thread and the 4300 lb rating are what put this in the heavy-duty end of the beam clamp range.

The B3055 steel beam clamp is cULus Listed, so it carries both US and Canadian listing for use as an electrical support component. That is usually what an inspector or a spec writer is looking for when conduit and cable support attachments have to be listed.

No. Vertical adjustment is built into the clamp itself, so you set the drop at the clamp rather than adding a turnbuckle or adjusting rod length at the other end. That saves a fitting on every hanger point when you are leveling a long conduit or trapeze run under existing steel.

It measures 10 in wide, 5.5 in high, and 5.5 in in length/depth, and weighs 10.4 lb each. Worth checking the 10 in width against your clearance if you are working in a tight ceiling cavity or close to a beam web, and worth factoring the 10.4 lb into the dead load when you are hanging a number of them.

The B3055-1X10PLN is plain finish steel, meaning uncoated, so it is intended for dry interior structural steel. Exposed exterior, a wash-down area, or a corrosive environment calls for a galvanized or electro-plated version of the clamp instead, or field coating after install.

Order Eaton B-Line part number B3055-1X10PLN. The B3055 is the series, 1X10 is the 1 inch-8 rod size configuration, and PLN is the plain (uncoated) finish. Quote that full string so you don't get shipped a galvanized or a smaller rod size.
