The Grade 80 Eye Foundry Hook (EFK Type) features a wide throat opening designed for foundries and pipe handling. It easily engages large or irregular loads where standard hooks cannot fit.
Wide Throat Opening: Latch-free, oversized mouth allows quick attachment to bulky items, molds, and large-diameter pipes.
High-Strength Alloy: Forged from quenched and tempered Grade 80 steel for maximum durability in heavy industrial use.
Certified Safety: Proof-load tested with a strict 4:1 safety factor and clearly marked Working Load Limits (WLL).
Corrosion Resistant: Features a durable powder-coated finish for extended life in demanding work environments.
*Designed for large diameter loads and high-heat environments
Product Features
Extra Wide Throat: Features a significantly larger throat opening than standard hooks. Allows connection to large diameter bars, casting molds, and trunnions where standard hooks cannot fit.
Foundry Ready: Ideal for sorting duties and high-heat foundry operations. The lack of a safety latch prevents mechanism failure caused by dirt, slag, or extreme heat.
Eye Connection: The eye top allows for versatile connection to chain slings (via Connecting Links), wire rope slings, or synthetic lifting belts.
Robust Material: Forged from Grade 80 Alloy Steel, Quenched and Tempered. The robust tip is engineered to withstand incidental contact (though tip loading should be avoided).

⚠️ 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.
