Simple and durable. Steel ballast is used to counter the weight of the door. The door goes up and the weights come down. The door goes down and the weights go up. An enclosure on one side of the door guides a series of weights. These weights are connected to the door by a cable through a series of pulleys. This is the Hanover Lift System.

High quality residential doors are supplied by RICHARD WILCOX.
