The DOS-IR® Slide Gate is designed to provide a shut-off on the control end of the pipe.  The sliding gate has a gasket to shut off flow through the culvert.  The gate can be opened slowly or held partially open to provide controlled discharge.

The DOS-IR® Flap Gate prevents backflow through the culvert.
