I have some various lengths and sizes of this stuff, and it's very nicely made:
Does anyone know if there are other manufactures of energy chain Like Igus?
I need about 12' of chain aproximately 1 to 1.5"H x 2" wide. What do you have that would come close and how much?
why not just get some from ebay, search "cable carrier"
There are two major players in the cable carrier business: Igus and KabelSchlepp Both are German companies with offices and manufacturing in the US (I think KabelSchlepp does more manufacturing in the US than Igus does). Both companies make top-quality products that are used in just about every industry.
Other companies that make cable carriers: (in no specific order)
