POLYCAST 600 Series Kit with DG0641D Slotted Ductile Iron Grate


Installation Chairs Included


POLYCAST 600 Series is a polymer concrete channel that has a built-in .65 percent slope that allows the system to achieve flow rates of 470 GPM.  The installation chairs tighten the joints between channels while aligning and leveling the drainage run.  Each installation chair is secured to the ground (using your own rebar), ensuring that the channels will not float during the concrete pour.
