END-FITTINGS

Wire rope sling

heavy-duty forged steel terminations engineered for high-load rigging, marine mooring, and crane hoisting applications, delivering up to 100% termination efficiency through poured resin/spelter socketing or cold-hydraulic swaging processes.

Engineered to achieve 100% efficiency of the wire rope's nominal breaking strength when properly poured or swaged.

Manufactured from alloy or high-grade carbon steel for extreme fatigue resistance and shock-loading durability.

Available in open clevis (pin-type), closed bail, and cold-swaged profiles to connect seamlessly with pad eyes, shackles, and master links.

Meets or exceeds ASME B30.26, Federal Specification RR-S-550, and API 9A standards for marine, offshore, and heavy lifting.
