Enhance the look of outdoor spaces with decorative drain grates on the channel drain system. The Dura Slope® Channel Drain Grate with classic tile design prevents leaves and debris from entering and potentially clogging drain pipes as water flows in. Adds a stylish look to driveways, pool areas, walkways, and other hardscapes. The decorative grate has an open surface area of 7.95 sq. in. per linear ft. and flow rate of 24.32 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. Made of raw iron, the grates will rust over time forming a protective iron-oxide patina that begins red-orange and ages to a deep, rich brown.
