B-Line Eaton series beam clamps, Malleable iron, 2", Supports pipe or rigid conduit, hardware included, Parallel pipe clamp, Hot-dipped galvanized

The B671-2HDG is sized for 2 inch pipe or rigid conduit. It is a parallel pipe clamp, meaning it holds the pipe or conduit running parallel to the beam flange it attaches to rather than crossing it. Pick the clamp size to match the trade size of the pipe or rigid metal conduit being supported, not the outside diameter of the insulation or jacket.

Yes. The B671-2HDG is malleable iron with a hot-dipped galvanized finish, which is the finish normally specified for exterior runs, parking structures, tunnels, water treatment plants and other wet or corrosive areas. For dry interior work an electro-galvanized or plain finish clamp is usually enough, so the HDG version is the one to order when the run leaves conditioned space.

The B671-2HDG carries a cULus Listing, which is what most inspectors and specs look for on conduit support hardware in commercial and institutional work in the US and Canada. It is catalogued for electrical use and supports rigid conduit as well as pipe.

No extra fasteners are needed. Hardware is included with the B671-2HDG, so the clamp arrives with what it takes to make up the assembly. You still supply whatever the clamp attaches to, such as the beam flange or the rod, and any strut or hanger rod in the run above it.

A parallel pipe clamp like the B671-2HDG carries the pipe or conduit alongside the beam, running in the same direction as the flange. A plain beam clamp just grips the flange and gives you a threaded hole for a hanger rod, so the pipe hangs below on rod and a separate ring or clevis. Use the parallel type when you want the run tight to the steel with no drop; use a rod-drop beam clamp when the pipe has to sit below the structure.

Order Eaton B-Line part number B671-2HDG. The B671 is the parallel pipe clamp series, the 2 is the 2 inch pipe or conduit size, and the HDG suffix is the hot-dipped galvanized finish. Other sizes and finishes in the same series carry different suffixes, so quote the full designation on the order to avoid getting a plain or electro-galvanized clamp.

Each B671-2HDG weighs 1.35 lb and stands 2 inches high. On long runs that dead weight adds up across dozens of supports, so count it into the load on the structure along with the filled weight of the pipe. The 2 inch height is also worth checking where you have tight clearance between the steel and a ceiling grid or duct.
