Installation Notes

Clevis grab hooks of this type are typically installed by riggers, contractors, or maintenance technicians familiar with chain rigging practices. Before attaching or removing any hook under load, ensure the chain and load are fully de-tensioned and supported. Inspect the hook and chain for wear, deformation, or corrosion before each use. Always verify that the hook size is rated and compatible with the chain size and the intended load before placing the assembly into service.
