B-Line B274RHDG Eaton series strut fittings and accessories, 3.93" Height, 5.67" Length, 1.68" Width, 1.76lbs, Steel, Right hand eight hole single corner gussetted wing fitting, Hot-dipped galvanized

The B274RHDG is the right hand version. Wing fittings are handed, so the gusset and the wing fall on one side of the corner only. If your strut corner runs the other direction, a right hand piece will put the bolt holes on the wrong face and you will need the left hand equivalent instead. Sort the handing at the opening before you order, because a right hand fitting cannot be flipped to serve as a left hand one.

Yes. The B274RHDG is steel with a hot-dipped galvanized finish, which is the finish you want for exterior runs, rooftops, parking structures, and wet or damp interior spaces where a plain or electro-zinc fitting would rust at the cut edges. Pair it with galvanized strut and galvanized hardware so you are not mixing finishes in the same connection.

Eight holes, split across the corner so you can bolt into strut on both legs of the joint. The fitting itself is what ships: strut nuts, bolts, and washers are separate items and need to be ordered with it if you do not already have them on the truck. Match the nut and bolt size to the channel you are fastening to.

It braces a 90 degree corner in a strut frame. The gusset is the folded reinforcement across the angle, and it is what keeps the joint from racking under load, which a flat plate or a plain angle bracket will not do as well. On trapeze supports, equipment stands, and cantilever brackets carrying conduit or pipe, this is the piece that stiffens the corner. If your joint is light duty and non-structural, a flat 90 degree angle bracket is the simpler choice.

Order by the manufacturer number B274RHDG, from Eaton's B-Line strut fittings and accessories line. If the fittings already installed are stamped with that number, this is the same part and will match hole pattern and handing. Check the stamping on one you are replacing rather than going by appearance, since the left hand version looks nearly identical in a photo.
