Capture runoff and add curved sections to the channel drain run with the Dura Slope® Channel Drain EZ-Track™ Radius Coupling. The patented U-shaped component features a +/- 3 degree range of angular motion for flexibility. EZ-Track radius couplings connect together to create tight curves, and also connect to Dura Slope Channel Drains. The customizable coupling can accommodate Dura Slope Channels from DS-091 (3.99 in. to 4.33 in. deep) to DS-114 (11.72 in. to 12.06 in. deep). The interlocking components snap into place to save time and labor with installation. Eliminates the need to measure angled cuts, saw, and miter pieces together. Made of high-density polyethylene (HDPE) containing UV inhibitors.
