The Ronstan Series 30 Ball Bearing Orbit Block - Double is a compact and lightweight component designed for various marine rigging applications. This double block, identified by part number RF35202, utilizes all-composite reinforced polymer materials for its construction, contributing to its strength-to-weight ratio. It features a precision design with an optimized number of ball bearings to minimize friction during operation. The use of fiber-reinforced composites in the block head, cleat arms, and beckets further reduces overall weight. This product is suitable for IT and marine businesses requiring reliable hardware for sailing systems. It addresses the need for efficient load management in applications such as mainsheet and spinnaker systems on dinghies up to 5 meters (16 feet), as well as halyard, vang, and backstay applications on similar sized boats. It can also be integrated into control line systems on larger yachts.
