B-Line Eaton series beam clamps, Material steel, Adjustable flange widths of 3" to 15", UFS beam clamp with weldless eye nut, 1"-8 thread/rod size, Pl

The B3294 UFS beam clamp adjusts across flange widths from 3 inches to 15 inches, so one clamp covers everything from a small bar joist chord to a heavy wide-flange girder. That range is why it gets specified on jobs where the steel varies opening to opening and nobody wants to stock four sizes of clamp.

Yes, it carries a cULus Listing, which covers both the US and Canadian marks. That matters on institutional and government work where the inspector wants a listed support component rather than a field-fabricated bracket holding the raceway or the fixture.

Forged steel, supplied plain (unfinished, no plating). Forged rather than cast or stamped is the reason it goes on heavy pipe and conduit runs. Plain steel is meant for dry interior structure; for a parking deck, a wash-down area, or anything exposed, specify a galvanized or plated version instead.

No. A UFS-style clamp like the B3294 grips the beam flange mechanically and adjusts to it, so the structural steel is never drilled, welded, or coated-through. That keeps the fire proofing and the paint system intact and keeps the structural engineer out of it, which is the usual reason a clamp gets chosen over a welded lug on retrofit work.

A C-clamp bites one edge of the flange with a set screw and suits light conduit or small rod. The B3294 spans the full flange, 3 to 15 inches, and terminates in a weldless eye nut sized for 1 inch-8 rod, so it is the heavy end of the range: large pipe, trapeze runs, and equipment hangers. Choose the C-clamp for a single EMT run; choose this when the load and the rod size grow.

No rod comes with it. The clamp ships as the assembly with its weldless eye nut only, so order 1 inch-8 all-thread cut to your drop length, plus the nuts and washers for the load end, separately.
