B-Line Eaton series Grip Strut two diamond plank, 120" Grating length, 4.75" Grating width, Aluminum, 1.5" Channel size, Grip Strut, .100" Thick

Each plank runs 120 inches long and 4.75 inches wide, with a 1.5 inch channel depth. On a walkway wider than 4.75 inches you lay multiple planks side by side across the supports, so plan your quantity off the total walk width rather than expecting one plank to cover it.

Yes. The two diamond Grip Strut plank is listed as OSHA compliant and is intended for safe, sturdy footing where non-slip walking surface is required, such as catwalks, platforms and equipment access.

No. What ships is the plank itself, model 21510 10 AL, in 120 inch length. Hold-down clips, saddle washers, bolts or self-drilling screws to secure it to your beams or channel supports are ordered separately, so add them to the same order if you want the job complete on one delivery.

The plank is aluminum, so it resists rust without any coating, which is why it gets specified for exterior platforms, wash-down areas and coastal or chemical environments where painted or plain steel grating corrodes. If your concern is galvanic reaction, note the plank material when you pick your fasteners and supporting steel.

The diamond count tells you how many rows of the pierced, raised diamond openings run across the width. This one is a two diamond plank at 4.75 inches wide, so it suits narrow runs, single-file catwalks, ladder rungs, stair treads and edge fill strips. For a full-width walkway or platform you either gang several two diamond planks together or move up to a wider multi-diamond plank to cut the number of pieces and fasteners.

It is formed from 12 gauge aluminum, and the channel is 1.5 inches, matching a 1.5 inch product height. That 1.5 inch dimension is what you subtract when setting your support elevation so the finished walking surface lands where the drawing calls for it.

Order Eaton B-Line part number 21510 10 AL. That number covers the aluminum two diamond plank, 120 inch length, 4.75 inch width, 1.5 inch channel.

Product weight is listed at 1.08 lb, and the aluminum construction is the reason crews pick this over steel grating for overhead and tower work. One person can carry a 120 inch section up a ladder, which steel plank of the same span usually will not allow.

Yes, aluminum plank of this gauge cuts with a circular saw and a non-ferrous blade, so a 120 inch piece can be trimmed to fit an opening or notched around a post. Cut ends should be supported and deburred, and remember the 1.5 inch channel legs carry the span, so do not remove them at a bearing point.
