Husky® drain clamps work in unison with Husky® drain connectors. They are designed for clamping the 10” drain in your Folding Frame Tank liner to shut off the supply of water from one tank to the other. This allows set up or tear down of multiple tank water shuttle operations. Our drain clamps are built with 6061-T6 aircraft quality aluminum. They are simple to use, very strong, compact and lightweight. Only 3 lbs.
