B-Line Eaton series strut fiberglass channel and fittings, 1" channel height, 240" channel length, 1.62" channel width, Polyester resin

That is exactly the reason to use it. The BFP42-240 is molded polyester resin rather than steel, so there is no galvanic corrosion, no rust bleed, and no need for field touch-up where cut. Typical uses are wastewater plants, pool and chemical rooms, coastal exteriors, and washdown areas where steel strut fails early. Where you need maximum load capacity or a welded connection, steel strut is still the better choice - fiberglass is a corrosion answer, not a strength upgrade.

The channel width is 1.62 inches, the standard 1-5/8 inch strut opening, so 1-5/8 inch channel nuts, clamps, and fittings engage the slot. Keep in mind the section is only 1 inch deep, so deep-throat fittings sized for the 1-5/8 by 1-5/8 inch profile may not seat the same way. For fiberglass runs, pair it with fiberglass or stainless fasteners so the hardware does not become the corrosion point.

Yes. Polyester resin channel cuts with an abrasive or carbide blade and needs no galvanizing repair at the cut end, unlike steel strut. Buying it in 240 inch sticks lets you field cut hanger drops and trapeze runs from one length. Wear respiratory and eye protection when cutting fiberglass, and seal or cap exposed ends per your own spec.

Order Eaton B-Line model BFP42-240. The BFP42 designates the fiberglass polyester channel profile and the -240 is the 240 inch length. Specifying the full number matters because the same profile is sold in shorter stock lengths.

One. At 9.6 lb for the full 240 inch length, the fiberglass channel is light enough for a single installer to carry and hold overhead while setting hangers, which is a practical reason crews pick it over steel strut on ceiling work. The length itself is the awkward part, not the weight.
