Installation Notes

Extension springs are typically installed by maintenance technicians or general trade professionals using basic hand tools. Always relieve tension from any existing spring assembly and confirm the anchor points are secure before installing a replacement. Verify that the rated safe load of the spring meets or exceeds the load requirements of the application before installation. Follow applicable local codes and equipment manufacturer guidelines for any assembly incorporating tension springs.
