The Green Pin Polar G-6333 Jaw & Jaw Turnbuckle is a cold-rated turnbuckle designed for tensioning applications in Arctic and sub-zero environments. The Polar-grade steel maintains impact toughness at extreme low temperatures, while the safety bolt and nut jaw connections provide vibration-resistant retention.
Key Features
- Polar-rated steel with verified low-temperature impact properties
- Jaw connections with safety bolt and nut retention
- Left-hand / right-hand threading for balanced adjustment
- Forged alloy steel, hot-dip galvanized
- Individually proof tested with certificate
- Charpy impact tested for sub-zero performance
Common Applications
- Arctic and sub-Arctic structural bracing
- Northern offshore platform tensioning systems
- Cold-climate marine rigging
- Any tensioning application in temperatures below -20C (-4F)
Why Green Pin?
Green Pin Polar turnbuckles are specifically engineered for cold environments where standard steel becomes brittle. Van Beest's Charpy impact verification ensures every unit maintains full rated performance in extreme cold.

Inspection & Safety
Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.
WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
