Ronstan’s Orbit Blocks are ideal for sheet applications on dinghies up to 16' and control line applications for small keelboats. These blocks feature a precision, two-stage bearing for reduced friction under high loads.
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 fiber-reinforced composites in the block head, cleat arms, and beckets.
