B-Line B276HDG Eaton series strut fittings and accessories, 4" Height, 4" Length, 1.62" Width, 1.96lbs, Steel, Fourteen hole double corner gussetted connection, Hot-dipped galvanized

The B276HDG is a fourteen hole double corner gusseted connection fitting. It ties two runs of strut together at a corner, and the gussets carry the load across the joint rather than leaving it all on the bolts. Fourteen holes means you have multiple bolt positions on each leg, so you can pick up as many strut slots as the load needs instead of being locked to one hole pattern.

Yes. It is steel with a hot-dipped galvanized finish, which is the finish specified for outdoor runs, rooftop supports, parking structures and damp interior spaces. Hot-dip coats all surfaces and cut edges, so it holds up better than a plain electro-galvanized fitting in weather. Field-cut strut ends and drilled holes still want cold galvanizing compound.

It measures 4 inches height by 4 inches length/depth by 1.62 inches width, and weighs 1.96 lb. The 1.62 inch width is the giveaway for fit: that is sized to sit on the face of standard 1-5/8 inch strut, so it lands flush on a 1-5/8 inch channel run rather than overhanging.

No. The B276HDG is the fitting only. Order your strut nuts, hex bolts and washers separately, in the same hot-dipped galvanized finish so you don't put plain or zinc hardware into a galvanized outdoor assembly and get dissimilar corrosion at the joint.

Use the gusseted type, like the B276HDG, where the corner has to hold its angle under load, such as a cantilevered conduit rack or a trapeze leg. The gussets brace the two legs against each other so the joint resists opening up. A plain flat angle plate is fine for light alignment work or where a second member already triangulates the frame, and it is easier to fit in tight spaces because it has no gusset sticking out into the corner.

Order B276HDG. That is the Eaton B-Line B276 fitting in the HDG (hot-dipped galvanized) finish, and HDG is the suffix that distinguishes it from the same fitting in other finishes. Give the full B276HDG on the purchase order so you don't receive a plain or pre-galvanized version.
