B-Line Eaton series Grip Strut four diamond plank, 144" Grating length, 9.5" Grating width, Steel, 2" Channel size, Plain, Grip Strut, 14 gauge steel

The Grip Strut four diamond plank runs 144 inches long and 9.5 inches wide, with a 2 inch channel depth. So one plank spans a 12 foot run and covers 9.5 inches of walking width. For a wider walkway, lay planks side by side until you reach the width you need.

Yes. The B-Line Grip Strut four diamond plank is listed as OSHA compliant, and it is made for safe, sturdy footing where non-slip surfacing is required, such as catwalks, platforms and stair treads.

No. This one is 14 gauge steel in a plain finish, meaning bare, uncoated steel. Indoors or in a dry area that is fine, but outdoors or in a washdown or corrosive environment it will need field painting or you should specify a coated or stainless version of the Grip Strut plank instead.

The diamond count is the number of serrated diamond rows across the width of the plank, so it sets the walking width. Four diamond gives you 9.5 inches of tread width per piece. A two or three diamond plank is narrower and is normally used for stair treads or single-file catwalks, while four diamond is the common choice for a wider walkway or where you plan to gang planks together for a platform.

The plank has a 2 inch height, which is the depth of the formed channel sides. Allow that 2 inch build-up when you set your support spacing and when you check clearance at doorways, thresholds and handrail height on a platform.

No fasteners are included. What you get is the 144 inch plain steel plank itself. Hold-down clips, bolts or welding to the supporting structure are supplied separately, so order your attachment hardware along with the planks.

The plank is listed at 3.8 lb, which is why a 12 foot length of 14 gauge Grip Strut is a one or two man carry rather than a crane pick. Light enough to stage by hand on a mezzanine or rooftop walkway.
