Ronstan RF35302 Series 30 Ball Bearing Orbit Block - Triple

Ronstan RF35302 Series 30 Ball Bearing Orbit Block - Triple boasts the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets.

Ronstan RF35302 Series 30 Ball Bearing Orbit Block - Triple Features:

• Lightweight, the lowest weight possible in orbit blocks
  
• Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement.
  
• High compression grade Acetal ball bearings and a secondary full-contact bearing
  
• The sheave and bearing system is supported by a fibre-reinforced load frame, computer modelled and optimised using advanced stress analysis methods
  
• The Dyneema Link, used in multi-sheave blocks, is produced from high spec SK75 fibre, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point
  
• Simple, versatile and secure attachment
  
• The single block is easily lashed to an attachment point, and can also accept Dyneema Links and shackles for a variety of efficient attachment alternatives
  
• Low profile and compact
  
• Ultra low profile thru-sheave becket
  
• Low friction 2-stage ball bearing system provides consistent performance over the full working load range
• Strong, lightweight fibre-reinforced cleat arms optimised at the required cleating angle
  
• Race-proven, carbon-fibre reinforced Ronstan C-Cleats give secure rope holding with low entry and exit efforts, and are fitted with fairleads for fast action from any angle
  
• Applications:
  
  • Mainsheet systems and spinnaker sheets on dinghies to 5m (16ft)
    
  • Halyard, vang and backstay applications on boats to 5m (16ft)
    
  • Control line applications on larger yachts
