The Wyr-Grid® Overhead Cable Tray Bottom Waterfall is designed to maintain a 1.38in (35mm) bend radius while transitioning fiber optic, power, and copper data cables from within the Wyr-Grid® wire rack down into racks in cables. Waterfalls simply snap on to 8in (203mm), 12in (305mm), 18in (457mm), 24in (610mm) and 30in (762mm) pathway sections, and can even be installed side by side to increase their overall width. All while keeping costs low thanks to a fast, strong, simple installation with fewer components. Black powder coat, 1pc.
