B-Line B123SS4 Eaton series strut fittings and accessories, 3.93" Height, 9.18" Length, 1.68" Width, 2.34lbs, Steel, Twelve hole triple wing fitting, Thickness 1/4 in, Stainless steel type 304

It's Type 304 stainless steel, not a plated or painted carbon steel fitting. That matters if you're mounting in a wash-down area, a wet process room, coastal exterior, or a corrosive plant environment where a zinc-plated fitting would bloom rust at the cut edges and bolt holes. Order number is B123SS4.

Material thickness is 1/4 inch. That's the heavy-gauge end of the strut fitting range, so it's meant for load-carrying connections and bracing rather than light conduit tack-up. Overall it measures 3.93 x 9.18 x 1.68 inches and weighs 2.34 lb.

A triple wing fitting is a three-plane bracket: it gives you bolt holes on three surfaces so you can tie strut runs together at a corner or junction where members meet on more than one axis. The B123SS4 carries twelve holes across those wings, so you can pick up multiple channel members or pick your bolt pattern to suit the joint instead of being locked to one hole location.

Yes. The B123SS4 is supplied as the fitting only, so the hardware to attach it to your strut, typically channel nuts and hex bolts, is ordered separately. If you're putting this in a corrosive or wet location, match the fastener to the fitting and buy 304 stainless hardware too, otherwise the plated bolts corrode first and you lose the benefit of the stainless bracket.

No certification applies to this fitting. It's a structural strut bracket, not a listed electrical device, so specs to work from are the 1/4 inch material thickness, the 304 stainless construction, and the twelve hole triple wing pattern.

Spec Eaton B-Line B123SS4. That's the manufacturer part number for the 304 stainless, twelve hole triple wing fitting in 1/4 inch material. Using the one number keeps the corner and junction brackets consistent across trades on the job.
