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

It measures 4 inches in height, 4 inches in length/depth and 1.62 inches in width, and weighs 1.96 lb. The 1.62 inch width is the number to check first: it is sized to sit against standard 1-5/8 inch strut channel face, so the fitting lands flush on the channel rather than overhanging it.

DURA GREEN is B-Line's green protective coating over the steel fitting. It is the finish to specify when a plain plated fitting would be marginal, such as damp mechanical rooms, parking structures, or covered exterior runs. If your job specifies a different corrosion class, match the fitting finish to the strut channel finish so you are not mixing coatings at the same joint.

Yes. The B276GRN is supplied as the steel fitting itself, with fourteen holes for bolting. Plan on channel nuts and bolts sized to your strut for every hole you intend to use. Order the nut finish to match the DURA GREEN fitting where corrosion matters.

A flat angle plate ties two channels at a corner but relies entirely on the bolts to resist the joint opening up. A double corner gussetted connection like the B276GRN adds a triangulated gusset at each corner, which is what you want on a loaded frame, a cantilevered bracket, or a trapeze that will see vibration. For light, non-structural alignment work the flat plate is the simpler pick.

Steel, with the DURA GREEN coating applied over it. That matters if the surrounding framing is aluminum or stainless, since mixing dissimilar metals at a bolted joint in a wet location invites galvanic corrosion. On an all-steel strut system it is a direct match.

The part number is B276GRN, from the Eaton B-Line series of strut fittings and accessories. The GRN suffix indicates the DURA GREEN finish, so if you are matching an existing run, check whether the fittings already installed carry that same suffix.
