  • Ergonomic Grip Latch: Designed with a specialized finger grip area, allowing operators to easily and safely open the hook even while wearing heavy work gloves.
  • Direct Clevis Attachment: Features a built-in clevis pin that enables quick, secure connection directly to Grade 80 lifting chains without extra coupling links.
  • Industrial Durability: Forged from premium Grade 80 alloy steel, securely supporting Working Load Limits (WLL) from 2 up to 8 tonnes with a reliable 4:1 safety factor.

Product Features

  • Ultimate Safety: The hook cannot open while under load. The positive locking latch engages with the hook body to form a continuous ring, preventing slip-offs.
  • Clevis Connection: Connects directly to Grade 80 chain links via a load pin. This streamlined design reduces weight and cost by removing the need for a Hammerlock.
  • Trigger Release: Designed with a recessed trigger that allows for easy, one-handed opening when the load is slack, but stays protected from accidental release during operation.
  • Certified Strength: Forged from high-strength Alloy Steel. Fully compliant with EN 1677-3 standards with a 4:1 Safety Factor.
Why Upgrade to Self-Locking Hooks?
Hook Type Latch Type Safety Level
Self-Locking Hook
(This Product)
Positive Lock Maximum Safety. Latch mechanically locks when loaded. Essential for construction sites and overhead lifting.
Sling Hook
(Standard)
Spring Latch Basic Retention. The spring latch only keeps the sling in place when slack. It does not lock under load.
