B-Line Eaton series strut pipe clamps and accessories, .104" height, 4.877" length, 1.25" width, 800 lbs, Steel, Include combination recess hex head m

It's a Type 304 stainless steel clamp, which is why it gets specified for wash-down areas, food and pharma plants, parking structures and coastal or exterior runs where a plain electro-galvanized clamp would bloom rust. Pair it with stainless strut and stainless strut nuts so you aren't mixing metals at the connection point.

It's an O.D. pipe conduit clamp, so it is sized to the measured outside diameter of the pipe or conduit, not to nominal trade size. Put a tape or caliper on the actual tube before ordering. This matters most on copper and tube, where the OD and the nominal size are not the same number.

No. The B2043SS4 ships with a combination recess hex head machine screw included. What is not included is the channel nut and the strut itself, so order those with the clamp if you're building the support from scratch.

It measures 4.877 in length/depth, 1.25 in width and .104 in height, and weighs .38 lb per piece. The .104 in figure is the strap stock thickness, so the clamp adds very little standoff behind the pipe. Use the .38 lb per unit when you're totalling dead load for a long overhead run with dozens of supports.

Different jobs. A one-hole strap fastens straight to the surface and is fine for light single runs. A strut clamp like the B2043SS4 bolts to channel, so you get one continuous support carrying multiple parallel runs, adjustable spacing, and the ability to move or add a line later without drilling the structure again. On a multi-conduit rack or a trapeze, the strut clamp is the right call; for one pipe on a block wall, a strap is simpler.

Order Eaton B-Line model B2043SS4. The SS4 suffix is the Type 304 stainless version, so if a submittal or an existing run calls out B2043SS4 specifically, a plain-steel B2043 is not the same part and will not hold up in the same environment.
