B-Line Eaton series Grip Strut four diamond plank, 120 Inch Grating length, 9.5 Inch Grating width, Aluminum, 2 Inch Channel size, Grip Strut, .080 In

The four diamond Grip Strut plank is listed as OSHA compliant and is intended for safe, sturdy footing where a non-slip surface is required. The pierced, serrated diamond openings shed liquid and debris rather than holding it, which is why it gets used on catwalks, platforms and access walkways in wet or oily areas.

Aluminum is the base material here, so the plank won't rust the way bare or painted steel does. That makes it a common pick for outdoor platforms, water and wastewater, food plants and coastal or chemical environments where a galvanized steel plank would eventually give up. If you need the higher load capacity of steel over long spans, specify a steel Grip Strut plank instead.

The diamond count is the number of rows of pierced diamond openings across the width of the plank, which is what sets the walking width. Four diamond gives 9.5 inches of width on this one. If you need a narrower tread, for stairs or a single pipe crossover, go to a two or three diamond plank; for a wide platform, run multiple four diamond planks side by side rather than hunting a wider single piece.

Order Eaton B-Line part 42012F 10 AL. The suffix breaks down as the 10 foot length and AL for aluminum, so it distinguishes this one from the steel and shorter-length planks in the same series.

Allow for the 2 inch channel depth below the walking surface, plus whatever your support clips and framing add. The 2 inch formed channel on each side is what carries the load between supports, so it must sit clear of conduit, piping or duct running beneath the platform.

Listed weight is 1.37 lb, and at 14 gauge aluminum the plank is light enough for one person to handle a full 120 inch length on a ladder or scaffold. That is the main reason crews choose aluminum over steel for retrofit work in occupied buildings where hoisting gear isn't practical.

The 42012F 10 AL is supplied as the plank itself. Support clips, hold-down hardware and the framing or channel the plank lands on are ordered separately, so scope those with your supports when you size the walkway.
