B-Line Eaton series strut fittings and accessories, 3.93" Height, 5.43" Length, 1.68" Width, 1.77lbs, Steel, Nine hole triple wing fitting, Thickness

The B124SS4 is a nine hole triple wing fitting from the Eaton B-Line strut fitting line. Triple wing means the plate is bent into three planes, so it ties strut channel together across three directions at a junction, with nine bolt holes spread over the wings for bolting to the channel with strut nuts. It measures 3.93 x 5.43 x 1.68 inches and weighs 1.77 lb.

It is type 304 stainless steel, so it suits outdoor runs, washdown areas, and damp mechanical rooms where a plain electro-galvanized fitting would rust at the cut edges. Pair it with 304 stainless strut, stainless strut nuts and stainless bolts, otherwise dissimilar plated hardware becomes the weak point in the assembly.

The material is 1/4 inch thick. That is heavy plate rather than light sheet stock, which is what lets a three way junction fitting carry load at the corner instead of deflecting. It also means your bolt grip length has to account for a quarter inch of fitting between the bolt head and the strut face.

No. The B124SS4 is the fitting only, a nine hole triple wing plate. You order the channel nuts and bolts separately, and in a 304 stainless application they should be stainless too. Count the holes you actually intend to bolt through, since not all nine are always used on a given junction.

Order by manufacturer part number B124SS4. That number carries the 304 stainless version of the nine hole triple wing fitting in 1/4 inch material. B-Line uses suffixes to denote finish on strut fittings, so the SS4 part number is what keeps you from receiving a plated carbon steel equivalent.

Each fitting weighs 1.77 lb. On a job with a few dozen junctions that adds up quickly for a hoisted or overhead assembly, so it is worth carrying into your dead load takeoff along with the strut itself.
