B-Line Eaton series strut fiberglass channel and fittings, 3.25" channel height, 120" channel length, 1.62" channel width, Polyester resin

The BFP22A-120 fiberglass channel runs 120 inches long with a 3.25 inch channel height and a 1.62 inch channel width. That height is a back-to-back (double) profile depth rather than the standard single 1-5/8 by 1-5/8 strut, so allow for the deeper section when you lay out hangers and clearances.

It is non-metallic. The BFP22A-120 channel is molded from polyester resin fiberglass, not steel, so it is the choice where corrosion, chemical exposure, or electrical non-conductivity rules out galvanized or stainless strut. Water treatment plants, coastal and wash-down areas, and chemical rooms are the usual reasons buyers move to fiberglass.

The BFP22A-120 is a 1.62 inch wide channel, which is the nominal 1-5/8 inch strut profile, so it is built around the same channel-nut geometry contractors already use. Eaton B-Line supplies fiberglass fittings and hardware for this series; where corrosion is the reason you chose fiberglass, pair it with non-metallic or stainless hardware rather than plated steel, or you have reintroduced the part that rusts.

11.5 lb for the full 120 inch stick. That is light enough for one person to carry and set overhead, which is a large part of why fiberglass gets specified over steel strut on long runs and ceiling work.

Go fiberglass when the environment attacks metal or when you want the support to be non-conductive: polyester resin channel like the BFP22A-120 does not corrode in damp, salt, or chemical atmospheres. Go galvanized or stainless steel strut when the run carries heavy mechanical loads, needs field welding, or where the deeper 3.25 inch fiberglass section will not fit the space. Fiberglass also cuts with ordinary hand tools and leaves no rusting cut edge.
