Ball Bearing Orbit Blocks'boast 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.

Applications:
Dinghy mainsheet systems, mainsheet fine tune systems on sportsboats & small keel boats, mainsheet systems on sportsboats using RF7 mainsheet swivel cleat unit, spinnaker and job sheets on dinghies - especially modern asymmetric classes and control line applications on larger yachts.
