Garage Door Repair

The mechanism should be installed at the center of the door. To determine the location, use a tape measure to figure the width of the garage door. Half this distance is the center. On the inside of the door, toward the top, draw a short vertical line down the center of the door. When you affix the drawbar (the mechanism for raising and lowering the door) at this line, the door weight will be evenly balanced at the lifting point.
