Determine the door weight and door height:

1. The pull weight of an extension spring is determined by the color code found on the end of the spring. See Chart Below.

2. Measure door the height.

3.Springs are only sold in pairs. If you cannot determine the color code, it will be necessary to weigh the door.

To Weigh Your Door:

1. Raise door completely. Disconnect power and lifting arm of garage door opener.

2. Fasten "C" clamps or vice grips under bottom rollers to retain door. With tension completely off extension springs, disconnect springs from track support.

3. Remove "C" clamps or vice grips and lower door by hand. Note that entire weight of door, which could exceed several hundred pounds, has to be lowered slowly by hand so more than one person is needed.

4. Set bathroom scale to zero and place under center of door and record door weight.

5. If door weight exceeds capacity of the scale, use 2 bathroom scales. Add a 2 x 4 with one end on one scale and the other on a second scale with the door perpendicular to the 2 x 4. Add the respective weight from each scale together to get the total weight of the garage door.
