Ronstan S40 BB Orbit Block,Cheek (RF45151)
Ball Bearing Orbit Blocks boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneema rope link head.
Their precision design provides the optimum number of ball bearings in loaded areas and eliminates them in inactive areas. Ineffective mass is reduced even further through fibre-reinforced composites in the block head, cleat arm and beckets.
