B-Line Eaton series strut fiberglass channel and fittings, 4" Height, 1.62" Length, 1.62" Width, 0.14lbs, Steel, Three hole 90° gussetted corner angle

Steel. Even though it is sold under the B-Line strut fiberglass channel and fittings family, this particular corner angle is a steel part, so treat it as a steel fitting when you are deciding on corrosion exposure or mixing it into a nonmetallic run.

The BFV371-2G is a three hole 90 degree gusseted corner angle. It ties two runs of strut channel together at a right angle, with the gusset carrying load across the corner rather than leaving it all on the bolts. Typical use is bracing a vertical strut post to a horizontal run on conduit racks, pipe supports, and equipment frames.

The BFV371-2G ships as the fitting alone. You order channel nuts, bolts, and washers separately, one set per hole, so a three hole angle needs three fasteners to land fully. Size the nuts to the strut you are bolting to.

Pick the gusseted version, like the BFV371-2G, where the corner sees real load or vibration. The gusset triangulates the two legs so the joint resists opening up under bending. A plain flat 90 degree angle is fine for light alignment work or where a diagonal brace already carries the load, and it is easier to fit into tight corners because nothing sticks out at the inside angle.

Order Eaton B-Line part number BFV371-2G. That is the full manufacturer designation for the three hole 90 degree gusseted corner angle, and there are no finish or size suffixes to add.

This is a steel fitting, so its service life outdoors or in a washdown, coastal, or chemical area depends entirely on the coating you select. In wet or corrosive environments, contractors normally move to a nonmetallic fiberglass fitting or a stainless equivalent instead of plain steel hardware.
