Installation Notes

Attachment of spring snaps should be performed with the connected load fully relieved of tension. Inspect the interlocking spring mechanism before each use to confirm full engagement and that the keeper closes completely. Do not exceed the rated load capacity of the snap or use it as a primary life-safety connector in overhead lifting without verifying applicable ASME or OSHA requirements. Replace any snap showing visible wear, deformation, or spring fatigue.
