Standards and Recommendations:

Hooks are fatigue rated and feature anti-fouling designs.
Ultimate Load is 4 times the Working Load Limit for all hooks.

Key Considerations:

Ensure proper engagement of the chain in hooks to minimize twisting.
Maintain a choke angle of 120 degrees or greater when using hooks as chokers.
Look for the color Gold to identify Crosby Alloy Hooks.
