Type 10 Turnbuckles
From their clean lines to the use of the highest grade materials and quality finish, Ronstan Type 10 turnbuckles are engineered to deliver performance while enhancing the appearance of any yacht, or tensile project.
Type 10 closed body turnbuckles have a sleek, modern profile with no sharp edges. They are easily adjusted by turning the unique adjustment nut, which is free to rotate within the sleeve on the turnbuckle body, and are secured with a quick turn on the locking nut. A sight hole is provided in the body to verify adequate thread engagement. With fine thread and single end adjustment, Type 10 turnbuckles are much easier to adjust than conventional turnbuckles, and the use of dissimilar but compatible metals for the threaded components avoids the risk of thread seizure. Toggles are designed with full lateral articulation for easy installation and connection compatibility.
Compact and lightweight fairleads for the deflection of sheets, halyards and control lines. RopeGlide™ Fairleads feature elliptical hole design, providing high tolerance for rope alignment variation and easy line threading. Smooth hard coat anodised finish available in 12mm single, double & triple and 16mm single versions for optimum deck layout.
- Compact, lightweight and low friction
- Elliptical hole design tolerates alignment variations, makes threading lines easy
- Simple and reliable design
- Low maintenance.
Large Continuous Line Furlers
Ronstan continuous line furlers for racing or cruising now come in two new larger sizes. Both offer standard furling for straight-luff sails such as Code 0, Screecher or Staysail, or can be combined with a top-down adapter for use with soft-luff sails such as coded asymmetrics, Reacher, Runner or Gennaker sails. Series 200 and 280 Furlers are easily adapted from standard to top-down, making them versatile and cost effective.
- Standard and Top-down options
- Advanced Drum Technology
- Maintenance free main bearing system
- Quick continuous line installation and removal system requires no tools.
Low Friction Rings
- Compact & lightweight
- Low friction
- Deep, secure lashing groove
- Simple & reliable design
- Low maintenance
A result of trickle-down from Grand Prix yacht racing Ronstan's range of Low Friction Rings provide an outstanding strength to weight solution where the absolute minimum friction of a ball bearing block is not required. That being said, the performance difference between well and poorly executed versions of these simple products is marked. The basic appearance of the Ronstan Low Friction Ring range belies an exacting development process that investigated, tested and delivered optimised performance in strength, weight, friction, line wear and security.
Ronstan Low Friction Rings are machined from high grade aluminium with a durable low friction anodised coating and are available in three sizes to suit lines up to 14mm (9/16").
Common applications for Ronstan Low Friction Rings on racing and cruising yachts:
- Jib leads
- Lazy jacks
- Furling line leads

Quick-Lock™Power, Performance & Intuitive Operation
The Ronstan Quick-Lock™ is the quickest and most user friendly winch handle available for racing
and cruising sailors alike. In addition to its super fast grab-and-release mechanism for foolproof single handed removal, it is the only handle to feature the patented auto quick-locking mechanism that lets you put the handle in the winch without depressing a lever or rotating a knob – it couldn’t be easier!
Ronstan Quick-Lock™ allows you to immediately place the drive head into the winch socket, without the need to rotate a knob or depress a button. Its stainless steel locking lever then retains the handle securely in place until you are ready to remove it.
Constrictor Textile Rope Clutch
Unlike all conventional clutches the Constrictor® system does not crush the rope between two metal surfaces. Instead, the loaded rope is held securely in a textile sock, itself attached to an anchor base. The rope runs freely through the sock in one direction, but is gripped instantly within the sock when running out in the opposite direction. This constrictor effect, patented by COUSIN Trestec, provides increasing holding power as the load increases.
- Stronger: The standard Constrictor® range provides 2x the holding power of conventional rope clutches, and custom solutions are available with holding power up to the break load of the rope!
- Lighter: The Constrictor is at least 3x lighter than conventional rope clutches.
- No Abrasion or Rupture: The unique textile sock closes like an octopus on the line, providing effective load distribution and outstanding grip; a result of fibre-to-fibre contact that is far less aggressive than traditional metal cams.
- Safely Release Under Load: The line can quickly and easily be released under load without the need of a winch, simply by pulling the control lanyard. This can be an important safety consideration in situations where immediate release is required.
- Remote Release System: The Dyneema® control lanyard can be extended to provide remote release, making it ideal for applications such as mast-head mounted halyard to eliminate mast compression loads and halyard creep.
