Ronstan RF55210 Series 55 Bb Orbit Block – Double Becket Swivel

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 allows 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 arms and beckets.
