3 Inch Positive Locking Pelican Hook

Hayn 3" Positive Locking Pelican Hooks are Type 316 stainless steel lifeline gate fittings with a positive locking mechanism that keeps the hook closed under load until deliberately released.
Strong Where It Matters

3" Inch Positive Locking Pelican Hook

The positive locking design is the critical safety feature here — a standard pelican hook can work open under the lateral loads and vibration that a lifeline encounters at sea, while the locking mechanism on this hook prevents accidental release without making intentional release difficult in an emergency. Available in machine swage configuration for imperial wire sizes 1/8" through 3/16" and metric sizes 3mm through 5mm, as well as a Handy Crimp stud option for 1/8" and 3/16" wire. A 4" version is also available for applications requiring greater gate clearance.

Engineered In America Every Hayn fitting is designed and manufactured at our facility in Rocky Hill, Connecticut — the same American workmanship that has set the standard for stainless steel rigging hardware since 1950.
Cold-Worked Production Hayn fittings are cold-worked, not cast. That distinction matters: the cold-working process refines grain structure, increases fatigue resistance, and produces a fundamentally stronger component — one built to perform when the load comes on it.
Precision Manufacturing Our Rocky Hill production floor runs CNC vertical mills, CNC lathes, large-capacity mill-turn centers, and waterjet cutting systems — all configured to produce hardware that meets exact specifications, every time.
75+ Years of Excellence Hayn has been engineering and manufacturing marine and architectural rigging hardware since 1950. That track record isn't just history, it's the design knowledge, failure data, and continuous improvement that goes into every product we make. 
  • Type 316 stainless steel construction for superior saltwater corrosion resistance
  • Manufactured in Rocky Hill, Connecticut to Hayn's proprietary tolerances
  • Precision-machined using advanced CNC manufacturing equipment



  • Engineered for seamless integration in marine and architectural rigging systems

  • Short lead times on both standard and custom components

  • Backed by 75 years of marine and architectural hardware expertise
