Installation Notes

Extension springs store energy under tension and should be installed and removed with appropriate hand tools and eye protection. Always relieve any existing tension from the assembly before removing the old spring. Verify that the mounting hooks or anchor points are rated to handle the spring load before installation. Follow all applicable local codes and manufacturer guidelines for the specific assembly being serviced.
