Installation Notes

Extension springs store tension energy and should only be installed or replaced by a qualified handyman or tradesperson familiar with spring hardware safety. Always relieve all tension from the existing spring assembly before removal. Use appropriate pliers or spring hooks rated for the load; never use bare hands to stretch or compress the spring beyond its rated deflection. Inspect the mounting hooks, pins, and anchors for wear before installing new springs.
