The range of Ronstan Orbit Blocks boast the highest strength-to-weight ratio available in small ball bearing blocks.

Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fiber-reinforced composites in the block head, cleat arms and beckets.
