Z887-12-HDG-GDC 12″ Heavy-Duty Catch Basin with Galvanized Frame & Ductile Iron Grate
The Z887-12-HDG-GDC is a high-performance 12″ wide catch basin system engineered for commercial and industrial drainage applications. Featuring a heavy-duty galvanized steel frame paired with a galvanized ductile iron slotted grate, this system is designed to handle dynamic loads while offering superior durability and installation efficiency.
Constructed from high-density polyethylene (HDPE), the basin body is lightweight yet exceptionally tough, with 0% water absorption and mechanical lock-in points for anchoring into concrete. Weighing under 15 lbs, it significantly reduces installation time—up to 75% less labor than traditional systems.
