B-Line Eaton series strut fiberglass channel and fittings, 1" channel height, 120" channel length, 1.62" channel width, Vinyl polyester resin

That is the main reason to buy it. The BFV42-120 channel is molded from vinyl polyester resin rather than steel, so it is non-metallic and won't rust the way plain or even galvanized steel strut does in wash-down areas, water treatment plants, coastal sites, or chemical rooms. Steel strut still makes sense indoors and dry where you want higher load capacity; pick the fiberglass where corrosion, not load, is the deciding factor.

The channel measures 1.62 inches across the face, which is the 1-5/8 inch nominal strut width, so hardware built for that standard profile lines up. Watch the depth: at 1 inch high this is the shallow profile, so anything that seats on the inside depth of a 1-5/8 x 1-5/8 channel may sit differently. Check the nut or spring height against the 1 inch dimension.

4.8 lb for the full 120 inch length, which works out to under half a pound per foot. That is light enough for one person to carry and set several sticks at a time overhead, and it takes strain off the anchors compared with a steel section of the same length.

No. BFV42-120 is the channel itself, one 120 inch length. Fittings, straps, channel nuts, and anchors are ordered separately. For a non-metallic run, plan on matching fiberglass or non-metallic fittings and hardware so you don't reintroduce a corroding steel part into a corrosive environment.

Yes, the 120 inch sticks are cut down in the field like any strut run. Because it is a vinyl polyester resin composite rather than steel, use an abrasive or carbide blade, wear respiratory and eye protection for the glass dust, and seal or coat the cut end per the job spec to keep moisture out of the exposed fibers.
