Springs used in garage door systems are often color-coded to indicate their wire size and weight capacity. This standardized system allows for quick identification of the correct spring for a specific door, ensuring proper balance and safe operation. For instance, a brown spring might signify a specific weight capacity, different from a blue or orange spring.
Correct spring selection is critical for safe and efficient garage door function. An improperly matched spring can lead to premature wear of the door opener, difficulty in opening and closing, and even potential injury. Historically, this system arose from the need for a simple, universal method to identify spring strength, replacing more complex and potentially inaccurate measurement methods. This standardized approach significantly improved safety and simplified repairs and replacements within the industry.
