B-Line B172SS6 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 in, Fits channel type B22 or B52A, Stainless steel type 316

The B172SS6 four hole splice clevis is made for Eaton B-Line channel types B22 and B52A. If your run is a different profile, this is not the fitting for it. B22 and B52A are the back-to-back and deeper channel profiles in the B-Line range, so confirm the channel marking on your existing strut before ordering.

It is stainless steel type 316, which is the grade specified for coastal, chemical, and washdown environments where plated steel would rust out. That makes the B172SS6 usable on exterior rooftop supports, food plants, and water treatment structures without a supplementary coating.

Four holes, meaning two bolt-and-nut sets per side of the joint to tie the two lengths of channel together. Channel nuts and bolts are separate items and are not part of the B172SS6 fitting itself, so add them to the order in a matching 316 stainless grade if the reason you chose this clevis was corrosion resistance.

1.62 in height, 7.24 in length, 2.12 in width, with a material thickness of 7/32 in. The 7.24 in length is what spans the joint and gives you two bolt positions on each side of the splice; the 7/32 in thickness is the steel section you are bolting through, so allow for it when picking bolt length.

A clevis wraps the channel rather than lying flat on one face, so it locates the two strut ends in line with each other while the bolts pull the joint tight. Use a flat plate splice where you only need to bridge one face and clearance is tight; use the B172SS6 four hole clevis where you want the joint held in alignment on a continuous run of B22 or B52A channel.

The fitting is steel, specified as stainless type 316, not a plating or paint over carbon steel. That matters on a splice because the bolt holes are cut edges: a plated part exposes bare steel at every hole and starts rusting there first, while a solid 316 part does not.

Order it as B-Line B172SS6. The SS6 suffix is the type 316 stainless version of the B172 four hole splice clevis, so if a drawing calls for plain B172 you are looking at a different finish, not the same part.

Each clevis weighs 2.66 lb. That is worth knowing on long overhead trapeze or cable tray runs, where a splice every few feet adds real dead load to the supports, and it also tells you these are handled one at a time rather than by the handful on a ladder.
