RONSTAN Orbit Blocks - Overview

Less friction, ultimate performance -
Ronstan Ball Bearing Orbit Blocks™ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneema® rope link head. Their precision design allows the optimum number of ball bearings in loaded areas and eliminates them in inactive areas. Ineffective mass is reduced even further through fibre-reinforced composites in the block head, cleat arms and beckets.

  • Ultra lightweight.
  • Highest working load in its class.
  • Simple and secure attachment. The Dyneema® Link is easily fitted and is retained securely by a moulded retainer clip.
  • Low profile and compact.
  • Fiddle block flexibility.
  • High performance cleating
  • Used for sheets and control lines on dinghies, sports boats and small keel boats. Control lines on larger yachts.

    Less fatigue, more control -
    Ronstan Ratchet Orbit Blocks. The world’s best ratchet block is now even better. It has all the holding power of its predecessor, but with superior rope wear performance. It’s lighter, and it’s the only ratchet block with both manual and full automatic modes.

    Control switches on both sides of the block remain accessible whether fitted on port or starboard side, and the NC-machined alloy sheave and simple mechanism ensures superb reliability and durability.

    It is essential equipment on racing dinghies and sports boats, and when you want the ultimate holding power.
