Ronstan RF35100 Series 30 Ball Bearing Orbit Block Single Swivel Shackle Hd Becket

Highest working load in its class

The Ronstan RF35100 Series 30 Ball Bearing Orbit Block
Single Swivel Shackle Hd Becket 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 RF35100 Series 30 Ball Bearing Orbit Block Single
Swivel Shackle Hd Becket 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
