Garage doors are heavy and the largest moving objects in your home.

Unless you have got plenty of experience and the right set of tools, you should never attempt it on your own. Those who have both of these things can benefit from the guide below.

What Is Garage Door Torsion Spring?

The standard garage door designs have torsion springs but some doors may have extension springs. To proceed with a repair, you need to know if your garage door has a torsion spring. 

If you see thick metal springs running above your door, it is a torsion spring assembly. You can see the springs end in metal pieces called cones. Torsions spring power your garage door through a drum, cable, and a heavy-duty shaft. 

There are thirty different sizes of torsion springs used in garage doors. Their size, length, and diameter are determined according to the size and weight of the door. The number of coils is another important measure for torsion springs.

Determine Number Of Springs

Your garage door can have either one or two springs. A solo spring system controls the left and right sides of the garage door during the operation. If your door has a single torsion spring, it’s best to replace it with a dual spring system. This system has two springs that control each side of the door. If your garage door features a dual spring system, the lengths could vary.

How To Measure Garage Door Torsion Spring?

Once you have determined that your garage door has torsion springs and their number, the next step is to measure them.

When the spring is not broken, measuring it is pretty simple. Use a measuring tape and determine the length between the first and last coil. Do not include the cones in the length.

If the spring is broken, you need to be extra careful. When the spring is in unwound state loosen the setscrews on the winding cone, keeping your fingers out of the spring. Once the cone is free to slide, remove any gaps between the coils and measure them.

For wound springs, measure the number of spring turns.

Now you need to determine the length of the unwound spring. Count off one coil for each turn. Record these measurements because you will need them to purchase a new set of springs.

You also need to measure the wire size. To do that divide the length of the wound spring by the number of coils. Let say the length of ten coils is 80 cm. The wire size comes out to be 8 cm.

Garage Door Torsion Spring Vs Extension Spring

There are two main types of spring systems, torsion spring and extension spring. Torsion springs are above your door whereas extension springs run along the length of the door. You will not find metal cones at the end of the later but coils. 

Extension springs fully extend when the door opens or closes and require more parts to work. Torsion springs do not fully extend but turn and are simpler in their operation. They allow controlled motion and need fewer repairs as compared to extension springs. Similarly handling a broken torsion spring is easier to handle.
