Installation Notes

Extension springs store energy under tension and should be installed and removed with appropriate hand protection to prevent injury if a loop slips. Ensure mounting points are rated to handle the spring load before installation. Always relieve tension from the assembly before replacing or inspecting the spring. General mechanical hand tools are sufficient for most installations.
