- Measure the length of the broken spring by first releasing its tension, then measuring both broken pieces and adding them together. Ensure you measure only the spring, not the cones.
2. Identify Left or Right Spring - Look inside the damaged torsion spring. If the coils are wound clockwise, it's a right-hand spring. If wound counterclockwise, it's a left-hand spring. Another way to check is to see if the spring points downward when unwound.
3. Measure Wire Diameter
- Measure the length of 20 coils and divide by 20 to find the wire diameter. For example, if 20 coils measure 5 inches, the wire diameter is .250. Accuracy is crucial; if 20 coils measure 4 7/8 inches, the diameter is .243. Confirm by measuring 40 coils and dividing by 40.
- Some torsion springs have a color-coding system: green indicates .243, gold indicates .250, and red indicates .225 (see the chart below for other colors), but measuring is more reliable.

4. Measure Garage Door Height
- Most garage doors are 7 or 8 feet high. Verify this with a tape measure. If your door is custom and taller than 8 feet, contact us for the appropriate springs.
