The Grade 80 Shortening Clutch Locking Type (SCL Type) safely adjusts chain sling lengths. Its integrated safety pin firmly locks the chain in place, preventing accidental release even when the load is slack.
Locking Safety Pin: Securely locks the engaged chain link to prevent accidental disengagement.
100% WLL Retention: The clutch design cradles the chain, allowing the sling to safely maintain 100% of its rated lifting capacity.
Direct Attachment: Built-in clevis pin allows for quick connection to Grade 80 chains without extra coupling links.
High-Strength Forging: Made from quenched and tempered Grade 80 alloy steel for maximum durability and strength.
Positive Locking: Features a spring-loaded Locking Pin. Once the chain is seated, the pin locks it securely, preventing accidental disengagement due to vibration or slack lines.
100% Load Capacity: The clutch pocket fully cradles the chain link, preserving its structural integrity. This allows the sling to be used at full capacity, unlike grab hooks that often require a 20% reduction.
Clevis Connection: Designed with an integral clevis pin for direct attachment to the chain leg or master link, ensuring a compact and robust assembly.
Safety Design: The locking mechanism is recessed to protect it from damage. Forged from Quenched and Tempered Grade 80 Alloy Steel.

Why Choose This?
Shortening Clutch (SCL / This Product)
Locking Pin
Maximum Safety. Chain cannot accidentally fall out. Ideal for critical lifts or when the chain might go slack.
Grab Hook (CGS / EGS)
Open Throat
Speed & Cost. Faster to adjust (just drop the chain in), cheaper, but chain can slip out if not under tension.

⚠️ 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.
