Dura Slope® EZ-Track™ Radius Couplings & Grates

Add curved sections to the channel drain run easily, eliminating the need to measure and make angled cuts and miter pieces together. The patented U-shaped component features a 2.4° range of angular motion for flexibility. Couplings connect together to create tight curves and also connect to the Dura Slope® channel drains.

Key Features

  • Patented flexible radius coupling works with Dura Slope channel sections to add curved sections in the channel drain run
  • 2.4 degrees of maximum deflection
  • Interlocking components snap smoothly in place
  • Couplings can connect together to make tighter curves
  • Grates available in a variety of materials, colors, and styles

Applications

  • Ideal for driveways, concrete and paver patios, courtyards, walkways, sports facilities, pool and spa areas, and fountains
  • Channel drains and trench drains are ideal for hardscapes to prevent mildew growth, concrete staining, and costly damage by capturing and conveying excess water for proper release downstream
  • The Dura Slope EZ-Track Radius Couplings and Grates work with Dura Slope Channel Drains as part of a coplete channel drain system to collect and direct water to drain pipes for proper release downstream or to an infiltration device

Installation & Maintenance

  • Connect to Dura Slope channels to make 2.4° bends; connect individual couplings together for tighter curves
  • Remove radius coupling grate to access area for cleaning and maintenance

Materials & Sustainability

  • Channels made of high-density polyethylene (HDPE) containing UV inhibitors
  • Grates made from plastic, galvanized & stainless steel, or cast & ductile iron
  • Onsite stormwater management protects the watershed downstream, and limits excess runoff which can lead to negative impacts such as erosion, pollution, and flooding
