Stop gates are designed to block water flow in open channel and available in almost any size. They are fabricated from aluminum or stainless steel and include reinforcements to limit deflection of the disc under the design head condition. The disc will have either one or two hand holes depending on the gate width for removing and installing the stop gate disc manually. The frame is lined vertically with UHMW/neoprene side seals and a neoprene flushbottom seal across the bottom. Stop gate frames can be either embedded or surface mount type.
