How to weigh your garage door:
1. Raise the door to the full position and secure with C-clamp or locking pliers (vice-grips) in track below bottom roller.
2. Remove the springs from the door.
3. For a one car opening, lower the door onto one bathroom scale in the center of the door and read the weight.
For a double door (16 ft. wide or larger) use two bathroom scales. Locate the scales two feet in from each side. Take the weight of both scales and add together for door weight.
4. Measure door height. Standard height is 7ft. 7ft doors require 25" x 42" extension springs. If your door is 8ft. high, refer to 27" x 48" extension springs.
