It is commonly used by homeowners, handymen, and garage door technicians to replace worn or broken springs on single- or double-car wood doors (9 ft or 16 ft wide), or as part of a full hardware refresh on fiberglass systems requiring four springs. The 150-pound rating ensures proper counterbalance, reducing stress on automatic openers and preventing premature wear on rollers, tracks, and hinges. Its galvanized finish withstands humidity and temperature fluctuations typical in garages, while the double-loop design minimizes the risk of detachment during operation?especially when used with safety cables. This spring is not intended for high-lift or commercial applications but excels in standard residential setups where dependable, code-compliant performance and ease of replacement are priorities. Always install with proper safety precautions, as extension springs are under high tension.
