What do the numbers on a torsion spring mean?
What do the numbers on a torsion spring mean?
The color code on a torsion spring indicates whether it is a “right wind” or “left wind” spring, with black indicating right wind and red indicating left wind. Beyond that the torsion spring is color coded so that technicians can determine the thickness, or gauge, of the wire.
How do I know what torsion spring I have?
Basically, you run a tape measure along the length of a spring, and take down the number of inches. Therefore, if your tape measure indicates that a torsion spring is 36 inches from one end to the other, that’s a 36-inch — or three foot — torsion spring.
How do you measure a garage door torsion spring?
In order to measure an unbroken spring, you will need to place a coin between two coils in the middle of the spring. Next, push the coils to the left and measure the length of the left side of the spring. Then push the coils to the right of the coin to measure the spring length to the right of the coin.

Is there a spring calculator for torsion springs?
The Springulator® is an easy-to-use, robust torsion spring calculator tool. With only a few required fields of input, the Springulator lets you check the stress of your torsion spring and determine a variety of size and design data.
Can you change the inside diameter of ID Springs?
If you currently have 1 3/4″ ID or 2″ ID springs, there is nothing to gain by changing the inside diameter from one to the other. The cost is the same within pennies, the springs have the same lift or torque rating, and they have the same cycle life.
How to measure garage door torsion spring length?
Inside diameter (90% of doors have a 2.0″ inside diameter) 3. Spring length (how long each spring is) 4. Spring orientation only worry about this if you have a 1 spring system (left wound or right wound). Generally, when looking from within the garage, if the spring is on the left side, it is right wound, and vice versa.
How many ID springs are in a door?
A third application would include times when springs with different inside diameters are available, and you need to check to see if what’s available will work. For example, many doors have 1 3/4″ ID springs, but some door companies carry only 2″ ID springs on their trucks.
