Installation Notes

Always release all tension from the existing spring assembly before removing the old spring. General hand tools are sufficient for most installations using this spring type. Ensure the anchor points and hooks are rated for at least the maximum safe load of 8.47 pounds before installing. Do not stretch the spring beyond the rated 3.5 inch maximum deflection, as exceeding this value may cause permanent deformation or failure.
