ToggleGarage Door Torsion Springs 101: How to Measure The Spring
At Springs On Wheels, we strive to provide the correct torsion springs for all your garage door repair needs. Whether you require standard or custom springs, we ensure you receive the ideal solution matched specifically to your specifications.
Step 1: Identify the Spring’s Wind Direction
Look carefully at the spring’s end to determine its wind direction. If the spring end points clockwise, it is left-wound. Conversely, if it points counter-clockwise, it’s right-wound. Typically, the winding cones and cable drums are color-coded to help: red signifies a right-wound spring, while black indicates a left-wound spring.
If you’re uncertain about your spring’s wind direction, don’t hesitate to reach out to our experts at Springs On Wheels for guidance.
Step 2: Measure the Wire Size of the Spring
Using a tape measure, measure the length of 10 or 20 coils on the spring that needs replacing. Cross-reference this measurement with the standard garage door torsion spring wire size chart provided by the Door & Access Systems Manufacturers Association (DASMA) to determine the correct wire size.
Step 3: Determine the Inside Diameter
Accurately measure the inside diameter of the torsion spring to the nearest 1/16th of an inch.
Step 4: Measure the Spring’s Overall Length
Use your tape measure to find the total length of the spring, rounding to the nearest quarter-inch.
Why Spring Wind Direction Matters
Understanding wind direction is crucial, as torsion springs must rotate correctly to safely and effectively operate a garage door. Using an incorrectly wound spring can prevent proper function and lead to safety hazards.
Measuring Wire Size Correctly
Instead of using calipers, it is recommended to measure using the distance between coils with a ruler or tape measure. This method provides more accurate results, especially for coated or slightly distorted springs.
Measuring Intact vs. Broken Springs
- Intact Springs: Measure 10 coils, then 20 coils separately, and reference these lengths on the DASMA wire size chart.
- Broken Springs: Combine broken halves on a flat surface to measure coil lengths effectively. Align the pieces precisely for accuracy.
Important Measurements for Ordering
When ordering replacement springs, ensure you have these measurements:
- Length
- Inside Diameter
- Wire Size
- Wind Direction
Having precise information ready ensures that Springs On Wheels can supply the perfect replacement springs for your garage door system.
