B-Line Eaton series strut pipe clamps and accessories, .104" height, 5.844" length, 1.25" width, Steel, Safety factor of 5, Include combination recess

The B2051SS4 is a Type 304 stainless steel strut pipe clamp. That makes it a reasonable choice for damp, washdown, coastal or lightly corrosive areas where a plain electro-plated clamp would rust out. The material is listed generically as steel in the spec table, with the description calling out stainless steel type 304.

It is an O.D. pipe conduit clamp, so it is sized to the actual outside diameter of the pipe or conduit rather than a nominal trade size. Match the measured O.D. of your run when picking the model, because copper tube, steel pipe and rigid conduit of the same nominal number do not share an O.D.

It means the published load rating for the B2051SS4 clamp is one fifth of the point at which the part would fail, so there is a five to one margin built into the rated load. Specifiers on hospital, industrial and institutional work often have to show that margin on a submittal, and it is stated for this clamp.

The clamp includes a combination recess, which lets it seat on more than one strut profile instead of being cut for a single channel. Practically, that is what keeps one clamp working across mixed strut on a job rather than stocking a separate clamp per channel type.

You can, but pairing Type 304 stainless with plated or galvanized strut and nuts puts dissimilar metals in contact, which is the usual reason people specify the stainless clamp in the first place. If the run is outdoors, in a pool room or a washdown area, carry the stainless through the channel nut and bolt as well; the B2051SS4 itself is the stainless part only.

Order it by manufacturer part number B2051SS4, Eaton B-Line series. That single model is the whole offering, so there is no finish or size option to specify alongside it.
