Product Description

Ronstan Series 30 Double Block

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.
