B-Line Eaton series Grip Strut two diamond plank, 120" Grating length, 4.75" Grating width, Steel, 2.5" Channel size, Plain, Grip Strut, 14 gauge

Each plank runs 120 inches long and 4.75 inches wide, with a 2.5 inch channel size and 2.5 inch overall height. That 4.75 inch width is the walking surface per piece, so for a wider catwalk or platform you lay multiple planks side by side across your supports and count 4.75 inches of coverage for each one.

The Grip Strut two diamond plank is listed as OSHA compliant, and the surface is built for safe, sturdy footing where non-slip is required. That is what makes it the usual pick for elevated walkways, mezzanine catwalks, and access platforms in plants and facilities where a smooth plate floor would be a slip hazard in oil, water, or ice.

Plain finish means bare steel with no galvanizing or coating applied. Bare steel will corrode in weather or in a wash-down area, so plain plank is the right choice for dry interior use or where you intend to paint or coat it after install. For exposed outdoor or corrosive service, specify a galvanized or coated version of the plank instead.

Two diamond refers to the number of diamond openings across the tread width. This one is the two diamond size at 4.75 inches wide, which suits narrow runs, single stair treads, and ladder or equipment access where you only need one plank width. Where you need a full walkway in one piece, a wider plank with more diamonds across covers more span without joining multiple pieces.

Order it by B-Line Eaton part number 22514 10 BL. That covers the two diamond plank, 120 inch length, 4.75 inch width, 2.5 inch channel, 14 gauge steel, plain finish. Confirm the channel depth against your support spacing before you order, since the 2.5 inch channel is what gives the plank its stiffness between bearers.

What ships is the plank itself, 120 inches of 14 gauge steel in plain finish. Hold-down clips, bolts, saddle washers, and any supporting framing are separate items, so plan on ordering your fasteners and support steel along with the plank to finish the run.

Product weight is listed at 2.8 lb, and the plank is 14 gauge steel in a 120 inch length. It is light enough for one person to carry and set in place, which is a large part of why perforated plank gets used instead of heavy bar grating on retrofit catwalks and equipment access platforms.
