About This

• Reinforced Fiberglass Structure: Made from polyethylene reinforced with 20% fiberglass, creating a stronger storm drain grate compared with standard plastic grates. The reinforced structure improves durability and helps the grate maintain shape under regular outdoor use.
• Designed for 12 Inch Catch Basins: Square drain grate designed to fit 12 inch catch basins, risers, and low-profile adapters. The drain cover sits securely on compatible drainage components used in yard and landscape drainage systems.
• Diamond Drain Grate for Debris Control: Diamond pattern openings help limit large debris such as leaves and small branches while allowing stormwater to pass through. Helps maintain consistent drainage flow in outdoor areas.
• Built for Yard and Driveway Drainage: Suitable for driveways, lawns, patios, walkways, and downspout drainage systems. The grate allows surface water to enter the catch basin and move through connected drain pipes toward the discharge location.
• Flow and Load Specifications: Open surface area of 53.1 sq in supports a drainage flow rate up to 162 GPM. When installed properly, the grate is suitable for Class B load conditions up to 175 psi, commonly used in residential drainage systems.
