6" Wide Polypropylene Trench Drain System with Ductile Rails

The 9931 incorporates a ductile iron frame with concrete frame anchors and grate. Recommended for situations requiring a heavy duty frame, grate and fully sloped channel, 9931 provides the perfect drainage solution. The frame and grate is capable of handling solid tire traffic and provides high resistance against impact of steel containers, struts and metal wheels.

The sturdy ductile iron framework will also accept any of the ductile iron gratings and covers to meet specific site requirements (Click here for grating options). The frame adds an additional height of 1.1" (28 mm) to channel units. Click here for System Overview with details of channel depth and system design.

The 9931 with frame locked down and grate is especially designed to prevent longitudinal or lateral movement.

The 095N 1/2 meter neutral channel section (inset photo) features side outlet connections on each side that allows for a 90º miter turn without requiring fabrication or allows for a side outlet connection. (Concrete frame anchor not shown on front).
