B-Line Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Steel, 1.5" Channel size, Plain, Grip Strut, 14 gauge stee

It's a 12 foot plank: 144 inches long by 9.5 inches wide, with a 1.5 inch channel depth. Formed from 14 gauge steel with a plain (unfinished) surface. The 9.5 inch width is what decides how many runs you need to cover a walkway, and the 1.5 inch channel height is the clearance you need to allow over your supports.

Yes, the four diamond Grip Strut plank is listed as OSHA compliant, and it's intended for safe, sturdy footing where non-slip walking surface is required. That's the usual reason it goes on catwalks, mezzanine walkways, platforms and equipment access runs in plants and utility yards.

The 41514 12 BL plank ships with a plain steel finish, meaning bare, uncoated carbon steel with no galvanizing or paint applied. Indoors and dry, that's fine as-is. Outdoors, in wash-down areas, or anywhere with chemical exposure, plan on field painting or specifying a coated version instead, because bare steel will surface rust.

The diamond count is the number of traction diamond rows across the width of the plank, so it tracks directly with how wide the walking surface is. This one is the four diamond version at 9.5 inches wide, which suits a single-run personnel walkway or a wider equipment access platform. Narrower two and three diamond planks cover ladder rungs, stair treads, and tight runs between obstructions. Match the diamond count to the clear walking width you need rather than mixing widths along a run.

No hardware is included with the 41514 12 BL plank itself, it is supplied as the bare formed plank. Budget separately for hold-down clips, saddle washers or bolts to fasten it to your supporting steel, and confirm your support spacing before you order quantity.
