B-Line Eaton series strut pipe clamps and accessories, .0966" height, 4.555" length, 1.25" width, Steel, Safety factor of 5, Include combination reces

The B2041HDG is a steel O.D. pipe conduit clamp with a hot-dipped galvanized finish, so it holds up outdoors, in parking structures, rooftop runs and other wet or corrosive areas where plain electro-zinc plating would rust out. For interior dry mechanical rooms the galvanized version still works, it just costs you nothing in performance.

It's a strut-mount clamp. The B2041HDG is part of the Eaton B-Line strut pipe clamp line and is made to seat in the channel and fasten with a strut nut and bolt. If you need to attach directly to concrete or masonry, you either run a length of channel first or use a one-hole/two-hole conduit strap instead.

By outside diameter. It is an O.D. pipe conduit clamp, so match it to the measured outside diameter of the pipe or conduit you're supporting rather than assuming a nominal trade size will line up. Copper tube, steel pipe and rigid conduit of the same nominal size all have different O.D.s.

It's rated with a safety factor of 5, meaning the published working load is one fifth of the failure point. That is the figure most electrical and mechanical specs call out for hanger and support hardware, so it's the number to put on the submittal.

It measures .0966 x 4.555 x 1.25 inches (height, length, width) and weighs .35 lb each. The 4.555 inch length is the figure to check against your strut layout and spacing, and the .35 lb unit weight is what you'd use to total a large hanger count for a load calculation.

Plan on it. The B2041HDG is the clamp itself, a steel hot-dipped galvanized O.D. pipe conduit clamp. To finish the job you'll also need the strut channel and the channel nut and hardware that fastens the clamp into it, and for exterior runs you want that hardware in a matching galvanized or stainless finish so you don't set up a corrosion cell at the connection.

Order Eaton B-Line part number B2041HDG. The HDG suffix is the hot-dipped galvanized finish, which is the distinction to watch for when a spec calls for exterior-rated support hardware.

The clamp includes a combination recess, which lets it accept more than one driver type on the fastener rather than locking you into a single bit. On a ladder with a pouch full of mixed drivers that saves a trip down.
