If your garage door isn’t closing all the way or making a lot of noise, you may need to replace the springs. Before installing them, you’ll need to measure them to ensure they are the appropriate size.
In this article, we’ll look at how garage door springs work and how to measure them.
What is the purpose of garage door springs?
Pulleys, cables, and springs power most sectional garage doors. The cable transmits the springs’ energy to move the door’s weight, while the pulleys assist in lessening the amount of effort needed to raise and control the movement of the doors.
If you have an extension spring garage door, two sets of pulleys and cables will be on each side. The first cable’s end is connected to the bottom of the door, which rises up and over a movable pulley near the upper corner of the garage door and then back to an anchored bracket fastened to the door track. As you shut the door, the springs and cable stretch out, generating tension that will assist in lifting the door when you next open it.
Two cables on each side of the garage door pass through the middle of the spring and are secured to track brackets on both ends. These are safety ropes used to keep the tension in the spring if it breaks. When replacing your door springs, you’ll need safety cables (or have them installed expertly) if yours aren’t already.
A winding cone secures the free end of the spring to the torsion bar. As the door closes, the extending cable causes the winding drum and torsion bar to spin and twist the spring into a loaded “torsioned” state. When the door is opened, the springs are relieved of their strain in a controlled manner, allowing the heavy door to be lifted to an open position.
The metal in the springs may lose resiliency over hundreds or thousands of opening and closing cycles, approaching a condition where they will need to be replaced, regardless of type.
How to measure your garage door springs
Before you can replace broken garage door springs, you’ll need to measure them to ensure you get the right ones.
Measure the length of your springs
To replace your garage door springs, you will first need to measure the length of the spring.
Once you have done so, you will need to purchase replacement springs of the same length. The old springs should then be removed from the garage door. This step is typically done by unscrewing the spring mounts from the door.
With the old springs removed, you can now install the new springs in their place.
Finally, screw the spring mounts back into place and test your garage door to ensure it is working correctly.
Measure the width of your springs
To replace your garage door springs, determine which type you have. The easiest way to do this is to measure the width of your spring. Torsion springs are usually one or two inches wide, while extension springs are typically half an inch wide.
Once you know your spring type, you can purchase the correct replacement spring at your local hardware store. Be sure to bring along the measurements of your spring and the weight of your garage door. With the correct replacement spring in hand, follow the instructions with your new spring to install it.
Measure the thickness of your springs
If you suspect your springs may need replacement, it is vital to measure their thickness. To determine whether your garage door springs need to be replaced or adjusted, you’ll need to measure their thickness.
To calculate the thickness of your garage door springs:
- Remove the winder handle from the centre of the spring.
- Determine the length of the exposed spring by measuring with a tape measure.
- Once you have this measurement, multiply it by two to get the thickness of the spring.
You must replace the spring if it is less than one-half inch thick. Otherwise, you can adjust it.
Compare your measurements to the size chart on the garage door spring replacement kit
Once you have measured your garage door springs, you can consult the size chart included in the kit to find the correct replacement springs for your door. It is important to note that there may be slight variations in size between different manufacturers, so be sure to select a size compatible with your door.
With careful measuring and selection, you can easily find a suitable garage door spring replacement kit for your needs.
Remove the old springs and install the new ones then test out the new springs by opening and closing your garage door a few times
