Ronstan Series 30 Orbit Block - 30 mm (1 3/16") - RF35101D

The Ronstan Series 30 Ball Bearing Orbit Block with Becket Option and Lashing Head boasts 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 fiber-reinforced composites in the block head, cleat arms and beckets. This block uses self-lubricating Nylatron® sheave and full contact bearing for high dynamic loads.

NOTE: To use the "Becket Option" add a line and splice or a Dyneema Link.
