B-Line B267RSS4 Eaton series strut fittings and accessories, 2.06" Height, 3.5" Length, 1.62" Width, .54lbs, Steel, Right hand three hole single corner wing fitting, Stainless steel type 304

The B267RSS4 is the right hand version of the three hole single corner wing fitting. Handing matters on a corner wing, because the wing turns toward one side only. Mirror-image corners on the same run need the left hand part number instead, so count your right and left corners before you order a quantity of B267RSS4.

Order it as B267RSS4, the Eaton B-Line series designation. The SS4 suffix is what tells you it is the type 304 stainless version rather than a plated steel fitting, so do not drop it when you spec the part on a purchase order.

Material is steel, in a type 304 stainless steel finish. That is the spec you want for damp, washdown, or exterior strut runs where an electro-galvanized fitting would bloom rust. For fully corrosive service such as coastal or chemical exposure, buyers typically step up to a type 316 stainless fitting instead.

The B267RSS4 is sold as the fitting only, three holes and nothing else. To hang it you still need hardware: channel nuts and bolts sized to your strut, and in a 304 stainless run you should match the fasteners to the stainless fitting rather than mixing in plated steel, which corrodes first and stains the joint.

A corner wing fitting brakes a strut run at a 90 degree corner and stiffens the joint, with three bolt holes spreading the load across both legs instead of pinning the turn on a single fastener. It is the piece you reach for on trapeze supports, pipe racks, and conduit runs that change direction. If you only need a flat splice on a straight run, a plain splice plate is the right part; if you need an angled brace rather than a square corner, use an angle fitting.
