4.1. Measuring the Length of the Spring
The length of the torsion spring is a critical measurement. Here’s how to measure it accurately:
- For Unbroken Springs:
- Measure the total length of the coiled portion of the spring.
- Do not include the cones in your measurement.
- Ensure the spring is relaxed and not under tension.
- For Broken Springs:
- Carefully slide the broken pieces together until the coils touch.
- Measure the combined length of the touching coils, excluding the cones.
- For Wound Springs:
- If the spring is wound, determine the number of turns by looking for paint or crayon marks that wrap around the spring.
- Deduct one coil length for each turn to estimate the unwound length.
- Alternatively, for standard 4″ cable drums on residential doors, deduct 8 coils for 7-foot doors and 9 coils for 8-foot doors.
- For larger industrial doors, unwind the spring if possible for direct measurement.
4.2. Determining the Wire Size
The wire size is the thickness of the wire used to make the spring. Measuring this accurately is crucial for selecting the correct replacement. Calipers and micrometers can be used, but the most accurate method involves measuring multiple coils.
- 10-Coil Method:
- Measure the length of 10 coils tightly pressed together.
- Use calipers for accuracy.
- Ensure there are no gaps between the coils during measurement.
- 20-Coil Method:
- Measure the length of 20 coils tightly pressed together.
- This method is more accurate and helps eliminate errors from counting coils.
- The 20-coil measurement should be approximately twice the 10-coil measurement.
Compare your measurements to a wire gauge chart to determine the wire size. The CONDUCT.EDU.VN website provides a comprehensive chart to assist with this comparison.
| 10-Coil Measurement | 20-Coil Measurement | Wire Size |
|---|---|---|

| 1 7/8″ | 4.76 | 3 3/4″ |
| 1 15/16″ | 4.88 | 3 7/8″ |
| 2″ | 5.08 | 4″ |
| 2 1/16″ | 5.26 | 4 1/8″ |
| 2 3/16″ | 5.55 | 4 3/8″ |
| 2 1/4″ | 5.72 | 4 1/2″ |
| 2 3/8″ | 5.95 | 4 11/16″ |
| 2 3/8″ | 6.02 | 4 3/4″ |
| 2 7/16″ | 6.19 | 4 7/8″ |
4.3. Measuring the Inside Diameter (ID)
The inside diameter (ID) is the distance across the inner circle of the spring. Accurate ID measurement ensures the spring fits correctly on the torsion tube.
- Using Calipers:
- Measure the distance from one inner edge of the spring to the opposite inner edge.
- Ensure the calipers are aligned properly for an accurate reading.
- Checking Cone Markings:
- Look for markings on the winding and stationary cones. Common markings include “175” or “134” for 1-3/4″, and “200” or “2000” for 2″.
- Use a flashlight to help read any faint markings.
4.4. Determining the Wind of the Spring
The wind of the spring refers to the direction in which the coils are wound. Torsion springs are either left-wound or right-wound, and it is essential to identify this correctly.
- Visual Inspection:
- Hold the spring vertically with the end of the coil pointing downwards.
- If the end of the coil points to the left, it is a left-wound spring.
- If the end of the coil points to the right, it is a right-wound spring.
- Hand Rule:
- Make a fist with your right hand, pointing your thumb down and into the “spring.” If your fingers curl in the direction of the end of the spring, it is a right-wound spring.
- Use your left hand for a left-wound spring.
- Garage Door Placement:
- Typically, the right-wind spring is on the left side above the garage door (as viewed from inside the garage), and the left-wind spring is on the right side.
4.5. Identifying the Type of Ends
Torsion springs come with different end configurations, and knowing the type of ends you need is important for a correct fit.
- Standard Ends:
- Most torsion springs have standard ends that are bent out slightly.
- Special Ends:
- Some springs require special ends to fit specific mechanisms.
- Examples include Crawford and older BarCol springs, which use end cones that may no longer be available.
If you need special ends, it is crucial to specify this when ordering a replacement spring.
5. Common Mistakes to Avoid When Measuring
