B-Line B274LSS4 Eaton series strut fittings and accessories, 3.93" Height, 5.67" Length, 1.68" Width, 1.76lbs, Steel, Left hand eight hole single corner gussetted wing fitting, Stainless steel type 304

B274LSS4 is the left hand version of the eight hole single corner gussetted wing fitting. Handing matters because the gusset and the offset wing are mirrored, so a left hand fitting will not sit correctly where the right hand orientation is needed. If you are bracing corners in both directions on the same run, you need both hands.

The base material is steel with a Type 304 stainless steel finish, which is what makes it suitable for damp, washdown, or corrosive locations where a plain electro-galvanized fitting would rust out. For food processing, water treatment, coastal, or exterior strut runs, that 304 spec is the reason to pick this part number.

It measures 3.93 in height, 5.67 in length/depth, and 1.68 in width, and weighs 1.76 lb. Use those figures to check clearance where the gusset lands against the adjacent strut, and to work out the hanging load when you have a number of them on a trapeze or wall bracket assembly.

It ties two pieces of strut channel together at a right angle and the gusset carries the moment at that corner, so the joint resists racking instead of relying on the bolts alone. Typical uses are wall-to-ceiling brackets, equipment frames, and bracing for conduit or pipe supports. Where you only need to join two channels flat with no corner stiffness, a plain flat plate or angle fitting is the simpler choice.

Order B274LSS4. That is the Eaton B-Line manufacturer part number for the left hand eight hole single corner gussetted wing fitting in Type 304 stainless. The SS4 suffix is the stainless designation, so quote the full number rather than just B274L when 304 material is required on the submittal.
