I wonder if they failed to use the correct size designation? Inches versus feet? The only one I can think of is 2”x2” Panduit. I suppose they make it in 3r, but it’s going to be plastic.
Organize cables effortlessly with the Panduit 2X2 FiberRunner Hinged Channel in Yellow 6' section from Telexpress Live Store. Durable, convenient, and visible solution for efficient cable management.
Thank you all for the suggestions and ideas. I indeed need a 2 inch x 2 inch square wire duct to fit on the bottom of a metal patio that is 4x4 beams and 2x2 cross members and they want to all look good. I found out that I can get 2x2 nema 3r special made from my electrical supply house.
