B-Line Eaton series beam clamps, 3000 lb, Steel, Beam clamp, 3/4"-10 thread/rod size, 1" flange width, Plain finish

Rated load is 3000 lb. That is the clamp's capacity, the actual allowable load on your hanger is whatever is lowest among the clamp, the rod, the beam, and the item being supported, so size the 3/4 inch-10 rod and the supported run to match.

It is built for a 1 inch beam flange width. Measure the flange thickness at the edge where the clamp will bite, if it runs thicker than 1 inch the jaw will not close on it and you need a wider-opening clamp. The clamp is meant to suspend hanger rod from an I-beam, so it grips the flange edge rather than bolting through the web.

Yes, it is cULus Listed, which covers both US and Canadian listings. That matters on inspected commercial and institutional work where conduit, cable tray, or busway supports have to be listed hardware.

This one is plain finish steel with no protective coating, so keep it to dry interior locations. For exterior, parking structures, or wet process areas, specify a galvanized or electro-plated version of the same clamp instead, plain steel will rust at the jaw and the tapped hole.

No. The B3050-5X10PLN is the clamp only. You order the 3/4 inch-10 all-thread rod, the hex nuts, and whatever hanger or trapeze fitting lands at the bottom separately.

Use a beam clamp when you are hanging off exposed structural steel and do not want to drill or weld the member, it clamps to the flange and gives you a tapped 3/4 inch-10 point for hanger rod. If your overhead is concrete deck rather than steel, a beam clamp has nothing to bite on and you want a drop-in or wedge anchor. For steel you are allowed to penetrate, a through-bolted beam attachment is the alternative.
