Ronstan (RF35212) Series 30 Orbit Double Block With Becket.

Ball Bearing Orbit Blocks™ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets.

Note: This block can take a rope dyneema head (RF9003-07) by removing the pin that secures the shackle head.
