Installation Notes

Installation does not require specialized tools for most light-duty hardware applications. Ensure the mounting point hardware — hooks, pins, or fasteners — is rated to handle the spring load before attaching. Relieve all tension from adjacent components before removing an existing spring. Inspect attachment points for wear or deformation that could cause premature spring failure.
