B-Line Eaton series strut fittings and accessories, 3.93" Height, 9.18" Length, 1.68" Width, 1.85lbs, Steel, Ten hole double wing fitting, Stainless s

The B273SS4 is a type 304 stainless steel fitting, not a plated carbon part. The material is steel with a stainless steel type 304 designation, which is what you want for wet, washdown, coastal, or corrosive process areas where an electro-galvanized fitting would bleed rust. Pair it with stainless strut and stainless hardware to avoid mixing metals at the joint.

It measures 9.18 inches long, 3.93 inches high and 1.68 inches wide, and weighs 1.85 lb. Use the 9.18 inch dimension when you are checking clearance along the strut run, and the 3.93 inch figure when the fitting has to clear an adjacent wall, duct, or conduit bank.

No. The B273SS4 is the fitting only, at 1.85 lb. Channel nuts, bolts and washers are ordered separately, and on a stainless job they should be stainless as well so the connection does not corrode at the fastener before the fitting does.

Type 304 stainless is the standard choice for outdoor, washdown and food processing environments, and that is the grade of this double wing fitting. For high chloride exposure, such as direct coastal salt spray or chemical processing, 316 stainless is the usual step up. No specific certifications are carried on this fitting, so if your spec calls out a listing by name, verify against the drawing.

Order it as B-Line B273SS4. The SS4 suffix identifies the type 304 stainless version, which is how it is distinguished from the plated carbon steel equivalents in the same fitting series. Give that full number to your distributor so you do not receive a galvanized part.
