The Green Pin G-5143 Polar Bow Shackle is engineered for extreme cold environments where standard shackles risk brittle fracture. The Polar range uses specially selected alloy steel with verified low-temperature impact properties, ensuring reliable performance in Arctic, sub-zero, and cold storage applications.
Key Features
- Polar-rated steel with verified low-temperature impact toughness
- Flat nut pin for secure, non-rotating closure
- Forged alloy steel, quenched and tempered
- Hot-dip galvanized for corrosion resistance
- Individually proof tested at 2x WLL with certificate
- Charpy impact tested for sub-zero performance
Common Applications
- Arctic and sub-Arctic lifting operations
- Cold storage and freezer facility rigging
- Northern offshore platforms and vessels
- Any application in temperatures below -20C (-4F)
Why Green Pin?
Green Pin Polar shackles are specifically engineered and tested for cold environments. Van Beest's Charpy impact verification ensures the steel won't become brittle when temperatures drop — critical safety assurance for cold-climate operations.
Safety & Standards
Every product we carry is individually marked with Working Load Limit (WLL), manufacturer traceability code, and country of origin. Inspection and mill certificates are available on request — email sales@slingcenter.com with your order number.
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
- WSTDA WS-2 and RS-1 — web and round sling design
- 49 CFR 393.102 to 393.130 — DOT cargo tie-down
- NACM — welded steel chain grade specs
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).
