Add a stylish touch to hardscape drainage with the decorative Dura Slope® Channel Drain Grate. Featuring an ornamental weave design, the drain cover blocks leaves and debris from entering and potentially clogging the pipeline as water flows in. Ideal for driveways, pools, walkways, and other areas. The decorative grate with weave pattern has an open surface area of 6.75 sq. in. per linear ft. and flow rate of 20.65 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.
