The Wyr-Grid Cable Side Waterfall is used in cable routing systems and designed to maintain a 3 inch (76mm) bend radius. The cable side waterfall helps transition fiber optic, power, and copper data cables from within the Wyr-Grid Wire Rack. It snaps on to an 8 inch (203mm), 12 inch (305mm), 18 inch (457mm), 24 inch (610mm), or 30 inch (762mm) pathway section without any tools needed.
