B-Line Eaton series beam clamps, Suspends hanger rod from I-beam, 1000 lb, Steel, Beam clamp, 1/2"-13 thread/rod size, 1/2" flange width, Plain

Rated at 1000 lb. That covers a single hanger rod carrying conduit racks, cable tray drops, strut trapeze, or pipe runs. The rating is for the clamp, so the working limit on the assembly is still whichever is lowest: the clamp, the 1/2 inch rod, or the beam itself.

Yes, the B3050 beam clamp is cULus Listed, which covers both US and Canadian listing. That is the line an inspector or a spec writer looks for when the clamp is supporting conduit, cable tray, or luminaire drops in a commercial or institutional building.

You get the clamp itself, model B3050-2X9PLN. The 1/2 inch all-thread, nuts, washers, and whatever hangs off the bottom (strut, tray hanger, pipe ring) are separate. Order the rod length to suit your drop and plan on a nut at the clamp to lock the rod.

A beam clamp grips the flange of an existing I-beam and gives you a tapped hole to hang threaded rod from, so you suspend the load without welding or drilling structural steel. The B3050 does exactly that job at 1/2"-13 rod. Where there is no beam to grab, you are into anchors into deck or concrete instead, which is a different attachment method entirely.

Steel, in a plain finish. Plain steel is fine for dry interior work such as conditioned spaces and finished ceilings. For damp locations, exterior canopies, or parking structures, specify a coated or galvanized version rather than the plain one.

Body dimensions are 2.125 in height, 1.375 in length/depth, and .625 in width. That is a compact footprint, useful when you are landing several drops close together along one flange or working tight to a duct or another trade's run.
