Grade 80 Self Locking Hook for Webbing Sling HFS type
No.502055
This Grade 80 Self-Locking Hook for Webbing Slings features a specially designed flat eye that prevents synthetic slings from bunching, providing a highly secure, auto-locking connection for safe and efficient lifting operations.
Specialized Flat Eye: Extra-wide, smooth attachment point designed specifically for flat webbing and round slings, ensuring even load distribution and minimizing sling wear.
Automatic Safety Lock: The latch automatically closes and locks as soon as tension is applied, preventing the hook from opening while under load.
Forged Alloy Steel: Drop-forged from quenched and tempered Grade 80 alloy steel to deliver exceptional tensile strength and long-lasting durability.
Heavy-Duty Trigger Mechanism: Features a robust, recessed trigger design that protects the locking mechanism from accidental impact and damage during rugged use.
Certified Performance: Engineered for overhead lifting with a 4:1 safety factor, finished with a highly visible powder coating for excellent corrosion resistance.
Flat Eye Design: Specifically engineered with a wide, flat eye to allow webbing slings to sit perfectly flat, extending sling life.
Self-Locking Safety: The hook closes and locks automatically under load. It cannot open while lifting, ensuring maximum safety.
Direct Connection: Eliminates the need for connecting links (Hammerlocks). Webbing can be sewn directly onto the hook.
Trigger Release: The recessed trigger design prevents the hook from being accidentally opened by catching on external objects.
Robust Construction: Manufactured from Forged Alloy Steel (Quenched & Tempered) with a 4:1 Safety Factor.
