Spruce up outdoor spaces with decorative drain grates as part of the drainage system. Stylish and functional, the Dura Slope® Channel Drain Grate has a timeless brick design prevents leaves and debris from entering and potentially clogging drain pipes as water flows into the channel. Ideal for driveways, pool and patio areas, walkways, and other hardscapes. The decorative grate has an open surface area of 11.35 sq. in. per linear ft. and flow rate of 34.73 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.
