Ronstan's Series 30 Ball Bearing Orbit Blocks boast the highest strength-to-weight ratios on the market. They are made almost entirely of high-tech, composite, polymer materials.

Ronstan's two-stage bearing system features high-compression grade Acetal ball bearings and a secondary full contact Nylatron sheave and full contact bearing for dynamic loads, which results in minimum friction.

Use these blocks in mainsheet and spinnaker sheet, halyard, vang, and backstay systems on dinghies and for control line applications on larger boats.

This lightweight double block has a versatile and secure becket attachment. Consider purchasing a RF9003-07 Dyneema Link to complement this block.
