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.

The pulleys acetal molded with precision ball bearings on stainless steel or Torlon® offer high performance and low friction. Can be fitted with a shackle in either of two planes to allow correct alignment of the block.
