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

The B3050-5X7PLN takes 3/4-10 threaded rod. That is the only rod size it is tapped for, so if your trapeze or hanger assembly runs 1/2-13 or 3/8-16 rod you need a different clamp in the series rather than an adapter.

It is sized for a 1 inch beam flange width. Beam clamps are cut to a specific flange thickness range, so measure the flange on the I-beam you are hanging from before ordering. A thicker flange will not seat correctly in this body.

Yes, it carries a cULus Listing, which covers both US and Canadian requirements. That matters on inspected commercial and institutional jobs where every support component in the raceway hanging system has to be a listed part.

The body is steel with a plain, uncoated finish. Plain steel is for dry interior use, mechanical rooms, above ceilings, interior plenums. For exterior, parking structures, or any damp or corrosive location, specify a galvanized or electro-plated version of the clamp instead.

No. The B3050 clamps onto the existing I-beam flange, so there is no drilling, welding, or coring of the structure. That is usually the deciding point on a retrofit where the structural engineer will not allow penetrations into the steel. You supply the 3/4-10 threaded rod and nuts separately.

Mechanically it is a general hanger-rod-from-I-beam clamp rated at 3000 lb with a 3/4-10 rod tap, so it suits any trade hanging load off structural steel with that rod size. Fire sprinkler work is a separate question: sprinkler hangers usually require components listed specifically to FM or UL for sprinkler service, so confirm your AHJ accepts this clamp for that use before speccing it on a fire line.
