Ronstan Series 40 Orbit Blocks
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 include mainsheet systems and spinaker sheets on dinghies, sports boats and small keel boats to 5m, halyard, vang and backstay applications on boats to 8m and control line applications on larger yachts.
