Installation Notes

Extension springs store tension energy and should be handled with care during installation and removal. Always relieve any existing load before replacing a spring, and use appropriate hand tools and eye protection. Ensure the mounting hooks or pins are rated for the spring load before securing. Follow all applicable local building and mechanical codes when integrating springs into door or gate hardware assemblies.
