Green Pin P-6036 Heavy Duty Bow Shackle (Safety Bolt & Nut)

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.

Standards & Compliance

Governing Standards

• ASME B30.9 — slings (web, round, wire rope, chain) inspection and use
• ASME B30.26 — rigging hardware (shackles, eye bolts, links, turnbuckles)
• ASME B30.10 — hooks
• OSHA 1910.184 and 1926.251 — general industry and construction sling safety

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).
