Installation Notes

Open S hooks should be installed by a qualified tradesperson familiar with load-bearing hardware requirements. Verify that the support point and connecting hardware are each rated to meet or exceed the intended load before installation. For suspended applications, ensure the hook seats fully on the support rod or anchor point to prevent unintended disengagement. Deform or close the hook ends with pliers where permanent attachment is required by code or application.
