B-Line Eaton series Grate-Lock traction grip female to female interlock, 240" Grating length, 12" Grating width, Carbon steel, 2.5" Channel size, Mill

The Grate-Lock traction grip plank runs 240 inches long by 12 inches wide, with a 2.5 inch channel size and a 2.5 inch product height. That's a 20 foot single run, so on a walkway or platform you cover the span in one piece rather than butting shorter sections together. Stated weight is 5.2 lb.

Female/Female means both long edges of this Grate-Lock plank are the female half of the interlock. Two female edges will not snap into each other, so to build out a wider walkway you need a mating male edge between them, typically a male/female plank. Use the female/female piece where both neighbours supply the male side, or as an edge run.

Traction grip is the surface pattern on this plank, and the stated application is safe, sturdy footing where non-slip is required. That is what separates it from a plain plank grating: the punched grip surface is what you want on elevated walkways, platforms and stair treads where crews are in boots.

The plank is formed from 14 gauge carbon steel, which is the structural body of the product rather than a sheet liner. Load capacity depends on your support spacing, so size the span off the manufacturer's load table for a 2.5 inch channel depth before you set your supports.

The finish is mill-galvanized carbon steel, meaning the zinc coating is applied to the coil before forming. Cut ends and punched edges are left bare, so for outdoor, coastal or wash-down service plan on field-touching cut ends with a cold galvanizing compound. For dry interior mechanical rooms and electrical platforms the mill-galvanized finish is used as supplied.

Order it as Eaton B-Line MG122514FF 20. The number reads out the configuration: 12 inch width, 2.5 inch channel, 14 gauge, FF for female/female interlock, 20 foot length.
