Counterweight up-and-over garage door
This is the classic up-and-over door: the leaf is balanced by two counterweights that rise and fall inside side columns, connected to the door by cables or chains. Because it is counterbalanced, it opens by hand with little effort and, if it has a motor, the motor carries less load. It is a simple, sturdy system that is easy to adjust and lasts for many years of daily use. It needs some space on each side of the opening for the columns; we measure it during the visit and calculate the counterweights against the weight of the actual leaf, especially if it is clad or has a pedestrian door.
