The Grade 80 Clevis Sling Hook with Ridge (CSR Type) is a high-strength, premium lifting hook engineered for secure load attachment in demanding industrial and construction material-handling operations.
Enhanced Safety Design: Features a specialized protective ridge built directly into the hook body that shields the safety latch, significantly reducing the risk of accidental unhooking during complex lifts.
Direct Clevis Connection: Designed with a precision clevis pin attachment that allows for fast, secure, and direct integration into Grade 80 chain sling assemblies without the need for additional coupling links.
Heavy-Duty Construction: Forged from expertly quenched and tempered Grade 80 alloy steel, providing exceptional durability, wear resistance, and long-term reliability in harsh operating environments.
Certified Performance: Rigorously proof-load tested to meet strict international lifting standards, ensuring a robust 4:1 safety factor for confident, heavy-duty load management.
Protective Ridge: Engineered with a raised ridge on the hook body. When dragged across floors (a common practice), this ridge hits the ground first, shielding the latch mechanism from crushing or shearing.
Clevis Connection: Features an integral clevis pin that connects directly to the chain link. This eliminates the need for a separate Hammerlock (Connecting Link), reducing weight and cost.
Heavy Duty Latch: Equipped with a strong, spring-loaded safety latch to ensure the load remains securely captured, even during slack conditions.
Standard Compliance: Forged from high-strength Grade 80 Alloy Steel (Quenched & Tempered) in accordance with EN 1677-2.
Design Advantage: The "Ridge" & Clevis

⚠️ Safety & Compatibility Notes
DO NOT mix Grade 80 components with other grades (G70, G100) in the same sling leg.
Always match Grade 80 chain with Grade 80 fittings.
Observe sling angle factors and WLL reductions during lifts.
Inspect regularly for: Wear (>10%), Cracks/Distortion, Corrosion, or Heat Damage.
