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.

COMMENT: I was unable to find these her where I live and I found them quickly on your site and as I stated before with the cables, the price was reasonable. by Jose V 9/5/2017
QUESTION: Please tell me if the ends of these springs are clipped? My old springs are rusty so no color code is visible but they do have clipped ends. Also they are longer than 25inches if I measure from the clips otherwise the spring itself is 25 in. We weighed the door and it is just under 240lb. So I would like to order the 240# replacement however when I click on it the choices go from 230 - 245... IS 245lb okay? by None N 6/5/2014

QUESTION: My extension springs are not color coded but the tag on the track reads spring E extension 2 ea. 25-42-100, 25 is the length, what does the 42 and 100 stand for? Thought maybe the 100 was weight? The doors are 9.00 x 7.00. by None N 5/27/2014
ANSWER: Dear shopper,<br />The spring will be 25 inches long compressed. The spring will stretch to 42 inches when the door is in a closed position. The 100 in the series of numbers is the pound weight of the door as it sits on a scale. Do not purchase these springs until you can verify that the actual weight of the door is 100 pounds.Springs non-refundable You can only achieve this is by actually putting a bathroom scale under the door a reading the actual weight of the door in question. The door needs to be free from all springs, wires and assemblies that do not produce any pull back on the actual weight of the door. by Tim W a
