The ball bearing Orbit Blocks ™ boast the highest ratio of strength-to-weight available. This is possible thanks to polymeric materials reinforced entirely composite and multiple mounting options.
Their precision design provides the optimum number of ball bearings to reduce friction to a minimum, while the weight reduction is achieved through the use of composite materials reinforced with fibres in the head of the block, in the arms of the cleat and becket.
