Low Friction Ring - 16mm Hole

Low Friction rings can be used as a lightweight alternative to a block in some applications. They are best suited for systems requiring relatively small line deflection angles, or for high static loads.
The design achieves a nicely rounded internal profile for smooth control line trim under load, and a deep external groove to retain the rope securely within the large shoulders when spliced into a loop.

Features:

• Compact & lightweight
  
• Low friction
  
• Large shoulder secure allowing for rope lashing
  
• Durable
  
• Simple & reliable design

Quick-Lock Winch Handle - Palm Grip - 200mm(8") Length

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 fool-proof single handed removal, it is the only handle to feature an auto Quick-Lock mechanism that allows you to place the drive head straight into the winch socket without the need to depress or rotate a knob - it couldn't be easier!

Quick-Lock™ Automatic Insertion
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.

Intuitive Grab & Release
The large easy to locate release button extends up the length of the handle providing fool-proof grab-and-release operation. This makes the Quick-Lock™ ideal for operation at full extension and with only one hand. Its intuitive nature makes it ideal for use by inexperienced and experienced crew alike.

Power in Your Hands
A precision ball bearing race in the hand grip provides free rotation for high speed or high power cranking alike and the refined ergonomics ensure efficient transfer of effort. 8" models cater to situations with restricted space and 10" handles provide greater mechanical advantage - the basis on which winch power ratios are calculated. Palm grip handles are the ultimate option where serious two-handed cranking is required.

Features:

• Auto lock-in latch
  
• Large grab-and-release button
  
• Single handed insert and release operation
  
• Ball bearing hand grips
  
• Lightweight forged construction
  
• Corrosion resistant Hardcoat anodised finish
