The Green Pin G-5151 Polar Dee Shackle (Flat Nut) is a cold-rated dee shackle with verified low-temperature impact properties for Arctic and sub-zero applications. The Polar-grade steel maintains toughness when standard shackle steel becomes brittle.
Key Features
- Polar-rated steel with Charpy impact verification
- Flat nut pin for secure closure
- Dee shape for inline load alignment
- Forged alloy steel, hot-dip galvanized
- Individually proof tested at 2x WLL with certificate
- Rated for sub-zero temperatures
Common Applications
- Arctic and sub-Arctic lifting operations
- Cold storage facility rigging
- Northern offshore and marine applications
- Any inline connection below -20C (-4F)
Why Green Pin?
Green Pin Polar dee shackles are specifically tested for cold environments. Van Beest's Charpy impact verification ensures the steel maintains its integrity when temperatures drop — essential safety assurance for cold-climate work.

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).
