The Mammoth is a hydraulic swing gate closer and hinge in one. An elegantly designed self-closing hinge that opens smoothly and closes gates consistently regardless of the outside temperatures. Force, closing speed and final snap action are all individually adjustable according to your needs. The Mammoth can be installed on left and right opening gates.

Two styles are available.

The heavy duty is for gates up to 5 feet wide and weighing up to 330 pounds.

The ultra heavy duty is for gates up to 6-1/2 feet wide and weighing up to 440 pounds.
