B-Line Eaton series strut fittings and accessories, .22" Height, 1.59" Length, 1.59" Width, .13lbs, Steel, End cap, Fits channel type B22, DURA GREEN

The B287GRN is made for B22 channel, which is B-Line's 1-5/8 inch wide, 1-5/8 inch deep double channel (two 1-5/8 sections welded back to back). The cap measures 1.59 by 1.59 inches across its face, so it closes off a square 1-5/8 profile. If your run is single 1-5/8 x 1-5/8 channel like B22 half-height or a 1-5/8 x 13/16 shallow strut, this is the wrong cap for that opening.

DURA GREEN is Eaton B-Line's green epoxy-type coating applied over the steel cap body. It is the same finish family used on B22 channel sold in DURA GREEN, so capping a green strut run with this part keeps the coating system consistent end to end rather than leaving bare steel exposed at the cut. Match the cap finish to the channel finish you ordered: a plain or pre-galvanized cap on a DURA GREEN run is a visible and corrosion-relevant mismatch.

No separate fasteners come with the B287GRN. It is a .22 inch thick steel cap that pushes onto the open end of B22 channel and holds by friction against the channel walls. At .13 lb each they are ordered by the piece, so count one per exposed channel end on the job, including cut ends on trapeze hangers and stub-outs.

The catalogue number is B287GRN, Eaton B-Line series strut fittings and accessories. The GRN suffix denotes the DURA GREEN finish; the base cap for B22 channel is the B287 with the finish suffix changing by coating. Specify B287GRN if you want the green coated steel version.

Cut strut leaves a sharp open channel end that snags hands, cable jackets and clothing, and on a coated run it exposes bare steel at the cut. The B287GRN closes that end off in steel with a DURA GREEN finish that matches green B22 channel. On exposed work in occupied buildings, inspectors and facility staff notice open channel ends, and the cap is the cheapest way to close the detail out.
