The Grade 80 Clevis C Hook (CCK Type) is a heavy-duty, latch-free lifting component with a wide throat opening. It is designed for fast, repetitive rigging operations where a standard safety latch would reduce efficiency.
Direct Attachment: Built-in clevis pin allows for quick, secure connection directly to Grade 80 chains without extra coupling links.
Wide "C" Profile: The large, latch-free opening enables effortless attachment to wire ropes, load rings, and various slinging points.
High-Strength Forging: Manufactured from EN 1677 forged alloy steel with a durable powder coating, providing a reliable 4:1 safety factor.
Certified Safety: 100% Magnaflux crack detected and individually proof-load tested to 2.5 times the Working Load Limit (WLL).
*Latch-free design for quick connection in rough terrain
Product Features
Forestry Specialist: Specifically designed for the logging industry. The "C" shape allows for quick, frustration-free connection of chains and wire ropes in difficult environments.
Latch-Free Durability: No moving parts to break. The open throat design prevents the hook from getting clogged with debris, ensuring reliability in mud, snow, and ice.
Clevis Connection: Features an integral clevis pin for direct, secure attachment to Grade 80 chain links, eliminating the need for extra connecting links.
High Strength: Forged from Grade 80 Alloy Steel (Quenched and Tempered) to withstand the severe shock loads and abrasion typical of forestry work.
