Protect drain pipes from potential clogging by blocking leaves and debris with the Dura Slope® Channel Drain Grate. The drain grate works with the Dura Slope Channel Drain to capture sheet flows from hardscapes and prevent leaves and debris from entering the pipeline. Also known as a drain cover, the cast iron grates are painted black to inhibit rust and over time form a protective iron-oxide patina. Grate has an open surface area of 20.85 sq in. per linear ft. and flow rate of 63.78 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.
