B-Line Eaton series Grip Strut stair tread, 288" Grating length, 7" Grating width, Aluminum, 2" Channel size, Stair tread, .080" Material thickness

The Grip Strut tread runs 288 inches long with a 7 inch grating width, and the channel depth is 2 inches. That 288 inch length is a full 24 foot piece, so it is normally cut down to your individual stair run width rather than installed as one tread.

Yes, the B-Line Grip Strut stair tread is listed as OSHA compliant. The plank is a non-slip walking surface intended where sure footing is required, which is what OSHA looks for on stair treads and elevated walkways in plants, mechanical rooms, and rooftop access stairs.

A single 7 inch wide plank covers a 7 inch tread depth. Most commercial stair treads run deeper than that, so two planks are typically set side by side per step to make up the required depth. Measure your stringer tread depth first and decide how many 7 inch widths you need per step before ordering the 288 inch length.

This one is aluminum, 14 gauge, at .080 inch material thickness. Aluminum is the choice for exterior platforms, wash-down areas, and coastal or chemical environments where a painted steel plank would rust at every cut edge. If the tread is indoors and taking heavy traffic or cart loads, a galvanized steel version of the same 2 inch channel profile is the usual pick instead.

What ships is the plank itself: a 288 inch aluminum Grip Strut section, 7 inches wide, 2 inch channel. Fasteners, end closure plates, and nosing are ordered separately, so plan your bolts and any carrier angles as a separate line on the job.

Channel depth sets how far the plank can span between supports. This tread is a 2 inch channel in .080 inch aluminum, which suits typical stair stringer spacing and short walkway spans. Where supports are set further apart, a deeper channel section carries the span instead. Confirm your support centers against the span you need before settling on the 2 inch profile.

Product weight is listed at 1.15 lb, and with the 2 inch channel height and .080 inch aluminum, this is a light plank to handle on a ladder or lift compared with a steel equivalent. That matters on rooftop equipment platforms and catwalks where dead load on the supporting frame is part of the design.
