B-Line B360HDG

The B360HDG is finished in hot-dipped galvanized steel, which is the finish specified for outdoor, damp, and corrosive environments such as rooftops, parking structures, wastewater plants, and exterior wall runs. Plain electro-galvanized or pre-galvanized fittings are the indoor-dry equivalent; if the strut run itself is HDG, match the fitting to it so you don't get dissimilar-finish corrosion at the connection.

Dimensions are 3.5 in length/depth, 1.87 in height, and 1.62 in width, at .53 lb each. The 1-5/8 in dimension matches standard strut channel width, so the fitting sits flush across the face of a 1-5/8 in channel rather than overhanging it.

No. The B360HDG is supplied as the bracket alone, a hot-dipped galvanized steel two hole corner angle. Order the channel nuts, spring nuts, bolts, and washers separately, and specify them in a matching hot-dipped galvanized finish so the whole assembly weathers the same way outdoors.

For a right angle joint between two runs of strut, installers typically use one angle on each side of the joint so the connection is not loaded in torsion off a single face. At .53 lb apiece the B360HDG adds almost nothing to the hanging weight, so doubling up at corners is normal practice on rooftop and exterior racks.

It is steel, so it can be cut or welded, but hot-dipped galvanizing burns off at the weld and the exposed steel will rust unless you re-coat it with a cold galvanizing compound. For exterior work most specs call for bolted connections through the existing holes rather than field welding, which keeps the zinc coating intact.
