Installation Notes

Extension springs store tension energy and should be handled with appropriate caution during installation and removal. Always release any existing load from the mechanism before replacing a spring. Standard hand tools are typically sufficient for hook-style single loop springs. Inspect mounting anchor points for wear or damage before installing the new spring to ensure a secure connection.
