Like the POLYCAST® 500 and 600 channels, the 650 catch basins can have both the Hardnose and Duraguard® frames on top of them. This is what turns the 650 catch basins into the 750 catch basins.
The Duraguard® frame is a polyethylene composite material that can improve heavy load performance for the catch basins.
The Hardnose frame is designed for the most hard vehicle traffic and applications. Made from cast iron, this frame designed to sit on top on the catch basin and hard wheel forklifts, industrial equipment and construction equipment.
