B-Line Eaton series Grate-Lock traction grip female to female interlock, 144" Grating length, 9" Grating width, Carbon steel, 2.5" Channel size, Mill-

Each Grate-Lock MG92514FF 12 plank runs 144 inches long by 9 inches wide, with a 2.5 inch channel height, and weighs 4.4 lb. That weight is why crews can set a 12 foot run by hand without a lift, and the 9 inch width means you plan your walkway in 9 inch increments across the span.

Female/Female means both long edges of the MG92514FF 12 plank are female profiles. It will not interlock directly with another female edge, so it pairs with a male-edged plank between runs, or sits as an end or standalone plank in the walkway. Lay out the run before ordering so you know how many male/female and female/female pieces the width of the platform needs.

The traction grip surface is made for safe, sturdy footing where non-slip is required, which is the usual reason it gets specified on catwalks, platforms and equipment access runs. The plank is carbon steel with a mill-galvanized finish, so it is intended for the kind of damp or exposed service where bare steel would rust out.

It is formed from 14 gauge carbon steel with a 2.5 inch deep channel section. The depth of that channel, not just the sheet thickness, is what carries the load between supports, so space your bearing points to suit the traffic the walkway sees.

Order it as Eaton B-Line MG92514FF 12. That breaks down as 9 inch width, 2.5 inch channel, 14 gauge, female/female interlock, in the 12 foot (144 inch) length.

Mill-galvanized carbon steel is the standard choice for general industrial and outdoor plant walkways, and that is what the MG92514FF 12 is. Cut ends and drilled holes expose bare steel, so field-touch those with a cold galvanizing compound. For washdown, coastal or chemical service, a stainless or heavier hot-dip grating is the better call.
