| Spring Type | Pros | Cons |
|---|---|---|
| Extension Spring | Suitable for heavy doors, can handle high loads | May be more expensive, can be noisy during operation |
| Retractor Spring | Suitable for lighter doors, easy to install, quiet during operation | May not be suitable for heavy doors, can be prone to wear and tear |

Here is a table showing the recommended spring sizes for 16×7 garage doors:
| Garage Door Size | Spring Size (UM or N)** |
|---|---|
| 16×7 | 20 (6.25 inches in diameter, 10.5 inches long) |
| 16×7 | 25 (7.5 inches in diameter, 12.5 inches long) |
| 16×7 | 30 (8.5 inches in diameter, 14.5 inches long) |
| Spring Type | Recommended Spring Size |

| Extension Spring | 20 or 25 |
| Retractor Spring | 30 |
Key Considerations
When choosing the right spring size, there are several key considerations to keep in mind:
- Door Weight: Lighter doors require smaller springs, while heavier doors require larger springs.
- Load Capacity: The load capacity of the garage door should be matched to the load it will be supporting.
- Door Material: The type of door material (wood, metal, or fiberglass) affects the recommended spring size.
- Structural Integrity: The garage door and surrounding structure must be able to support the weight of the spring.
Error to Avoid
When choosing the wrong spring size, there are several common errors to avoid:
- Choosing a spring that is too small: This can lead to premature wear and tear on the spring, as well as damage to the garage door and surrounding structure.
- Choosing a spring that is too large: This can lead to uneven weight distribution on the garage door, which can cause it to sag or collapse.
How to Choose the Right Spring Size
Choosing the right spring size for your 16×7 garage door can be a bit tricky, but here are some steps to follow:
- Measure the door: Measure the width and height of the garage door, as well as the distance between the hinges.
- Determine the load capacity: Determine the maximum weight that the garage door can support.
- Choose the correct spring size: Based on your measurements and load capacity, choose the correct spring size for your garage door.
- Consult a professional: If you are unsure about choosing the right spring size, consult a professional garage door technician.
Conclusion
Choosing the right spring size for your 16×7 garage door is crucial for ensuring the structural integrity of the garage door and surrounding structure. By considering the key factors mentioned above, you can make an informed decision and choose the correct spring size for your garage door.
