B-Line Eaton series strut fittings and accessories, 1.62" Height, 7.24" Length, 2.12" Width, 2.66lbs, Steel, Four hole splice clevis, Thickness 7/32 i

It is steel in a type 304 stainless finish, which is what you want for exterior runs, wash-down areas, and damp mechanical rooms where a plain electro-galvanized fitting would rust at the bolt holes.

Material thickness is 7/32 inch. That is the load-bearing section of the fitting, and it is the number to compare against a lighter stamped splice plate when you are joining a run that carries real weight.

It measures 7.24 inches long, 2.12 inches wide and 1.62 inches high, and weighs 2.66 lb. The 7.24 inch length is the one that matters on the job: you need that much clear strut either side of the joint, so plan your cut so the splice does not land on top of a hanger or a beam clamp.

The B172SS4 is the clevis fitting only, with four holes for fasteners. Order channel nuts and hex bolts separately, and in stainless to match the 304 stainless fitting, otherwise you set up galvanic corrosion at exactly the joint you are trying to protect.

Order it as Eaton B-Line B172SS4. That suffix is what identifies the type 304 stainless version, so quote the full number rather than the base B172 when you are matching an existing stainless run.

A clevis like the B172SS4 wraps the channel rather than sitting flat on one face, so it takes the joint in both directions and is the piece to use where the run is loaded or the splice lands mid-span. A flat splice plate is the simpler choice for a light, well-supported joint. With 7/32 inch material and 2.66 lb of fitting, the B172SS4 is the heavier-duty answer of the two.
