Add aesthetic appeal to the drainage system with the decorative Dura Slope® Channel Drain Grate featuring the Ville slot design. This ornamental design drains water away while blocking leaves and debris from entering and potentially clogging the drain system. The decorative grate has an open surface area of 10.07 sq. in. per linear ft. and flow rate of 30.90 GPM per linear ft. Rated for NDS Class C Loads (up to 325 PSI) when properly installed; rated for NDS Class D loads (up to 575 PSI) and H-20 rated when properly installed with the Ductile Iron Frame (DS-200H); ADA compliant and heel-proof. The grate is made of ductile iron and will rust over time forming a protective iron-oxide patina that begins red-orange and ages to a deep, rich brown.
