B-Line Eaton series Grip Strut stair tread, 576" Grating length, 9.5" Grating width, Steel, 2" Channel size, Mill-galvanized, Stair tread, 14 gauge

The Grip Strut stair tread, model T42014N 48 GL, is 576 inches in grating length with a 9.5 inch grating width, so the 9.5 inch dimension is the walking depth of each step and the length dimension is what spans the stringers. Channel depth is 2 inches. Measure your stringer-to-stringer opening against the length figure before ordering, since the tread is supplied at a fixed size rather than cut to order.

Yes. The B-Line Grip Strut stair tread is listed as OSHA compliant, and its purpose is safe, sturdy footing where non-slip walking surface is required. That covers plant stairs, mezzanine access, catwalk landings and rooftop equipment stairs where a facility needs a documented slip-resistant tread.

Match three things: the stringer-to-stringer length, the tread depth, and the channel depth that sets the mounting height. This Grip Strut tread runs 9.5 inches in grating width with a 2 inch channel height, and is identified as model T42014N 48 GL. If your existing steps are a different depth or a shallower channel, the new tread will sit proud or leave a gap at the nosing, so confirm those two numbers on a step you pull before you order the full flight.

The tread is steel with a mill-galvanized finish. Mill galvanizing is applied to the coil before forming, so the cut edges and pierced openings are left bare steel and will show rust first in wet or chemical exposure. It is a reasonable choice for covered exterior stairs and general industrial interiors. For constant wet service, corrosive wash-down, or coastal exposure, specify a hot-dip galvanized-after-fabrication or stainless tread instead.

14 gauge is the steel thickness of this Grip Strut tread, and combined with the 2 inch channel depth it is the common choice for normal foot traffic on industrial stairs. The 2 inch channel is what carries the span, not the gauge alone. If you are dealing with unusually long spans between stringers, cart or wheeled loads, or a spec calling out a specific uniform load, move to a deeper channel or heavier gauge rather than assuming this one covers it.

What ships is the tread itself, described as a steel Grip Strut stair tread in 14 gauge with a 2 inch channel. Fasteners and any stringer clips or angle supports are separate items you need to add to the order, so plan the bolt and washer count for your stair before the crew shows up.

Grip Strut in this configuration is built and sold as a stair tread, a 9.5 inch deep step with a 2 inch channel. The same perforated non-slip surface is used for walkways and platforms, but those are ordered as plank or grating sections in the run length you need, not as fixed-depth treads. For a landing or catwalk, order the plank or grating version; use this one where you are replacing or building individual steps.

Product weight is listed at 3.8 lb, so a single tread is a one-person carry up a stairway. That matters when you are retrofitting treads on an existing stair in an occupied building and have no crane or hoist access.
