    602325 Ronstan Ronstan Series 55 Ball Bearing Orbit Block RF55530

    The Ronstan Series 55 Ball Bearing Orbit Fiddle Block with Cam Cleat and Becket (RF55530) boasts 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.
