Garage Door Spring Color Chart

Garage door springs are color-coded to indicate their weight capacity. The color coding system is standardized across the industry, so you can be sure that a spring with a certain color will have the same weight capacity regardless of the manufacturer. The most common spring colors are red, green, yellow, and blue, but other colors may also be used. Garage door springs used as "counterbalancing" springs are dependent upon the weight of the door and the numbers of turns the torsion spring is "wound-up" to achieve the ideal balance of the door.

The following table shows the color coding for garage door springs:

Color	Weight Capacity
Red	Up to 100 pounds
Green	101-200 pounds
Yellow	201-300 pounds
Blue	301-400 pounds
Orange	401-500 pounds
Purple	Over 500 pounds

When choosing a garage door spring, it is important to select the correct weight capacity for your door. If the spring is too weak, it will not be able to properly support the door, and it could break. If the spring is too strong, it could put unnecessary stress on the door and its components.

In addition to the color coding system, garage door springs may also be marked with a number. This number indicates the spring's tension in pounds. The higher the number, the greater the tension.

When replacing a garage door spring, it is important to use a spring with the same color and tension as the original spring. Using a spring with a different color or tension could void your warranty and could cause damage to your door.

Here are some additional tips for choosing and replacing garage door springs:

Always consult with a qualified professional before attempting to replace a garage door spring.
Use a spring with the same color and tension as the original spring.
Make sure the spring is properly installed.
Inspect your garage door springs regularly for signs of wear or damage.
Replace any springs that are showing signs of wear or damage.
