⚡ At a Glance
- • Holding Strength: Heavy-duty machining and robust construction for dependable load-bearing performance
- • Best for: Sailboat owners, riggers and crews handling spinnaker halyards
- • Not ideal for: Applications requiring certified breaking load figures or detailed load ratings
316 stainless steel construction combines corrosion resistance with high strength. Quick-release plunger pin with a spot-welded split ring allows rapid opening, even under tension.
Quick release under tension - with a plunger pin and small steel ring
A plunger-style quick-release mechanism includes a small steel ring on the pin, allowing the snap bail to be withdrawn even when the line is under load. The split ring on the plunger pin is spot welded to retain the pin during heavy use.
Faster sail changes and emergency releases become practical, since the snap bail can be released while tension remains on the halyard. Users note reliable operation once the release action is learned.
Long-lasting corrosion resistance - with 316 stainless steel construction
Manufactured from 316 stainless steel, the alloy resists wear and corrosion in marine environments and withstands higher temperatures compared with lower-grade stainless steels. Machined edges and a careful finishing process reduce stress points that can accelerate wear.
Expect a longer service life in saltwater conditions with minimal maintenance, making it suitable for regular sailing use. The robust material keeps fittings looking tidy and functioning well over time.
Secure retention and tidy fitting - thanks to precision machining and spot-welded safety ring
An excellent machining process gives smooth edges and an attractive appearance, while the spot-welded split ring secures the plunger pin against accidental loss. Smooth geometry reduces snagging and friction where lines contact the shackle.
Secure, tight closure reduces the chance of accidental opening and lowers chafe on ropes. Durable build quality stands up to repeated handling on deck.
