Cover the Dura Slope® Channel Drain EZ-Track™ Radius Coupling with the solid grate to create an impervious surface. Ideal for installation to prevent concrete from getting inside the radius coupling. Unlike typical grates, the solid grate will not drain water into the channel drain. Attaches to the patented Dura Slope Channel Drain EZ-Track Radius Coupling and can be easily removed for cleaning and maintenance. Use around curved areas with the radius coupling as part of the Dura Slope channel drain system. Made of high-density polyethylene (HDPE) containing UV inhibitors.
