Ronstan Orbit Ball Bearing Block™ - Single Lashing Block with Becket
Ronstan Ball Bearing Orbit Blocks™ feature the unique orbital version of the Ronstan 2 stage bearing system. Recirculating ball bearings are positioned exclusively in the loaded area of the sheave and a second full contact bearing maintains low friction across the full working load range. Combined with composite reinforced polymer materials, Orbit Blocks™ offer maximum strength to weight ratio for high load and dynamic applications.
Single lashing blocks are designed for use with soft shackles or Dyneema loops and can be used for mainsheet and spinnaker sheet systems as well as halyard, vang and backstay applications on boats up to 5 m or for control lines on larger boats.
Built-in Becket - Orbit Single Swivel blocks have low profile moulded check plates optimized for use with the through sheave becket system, ultra low profile and light weight.
SP and High Load Version- Available with a self lubricating Nylatron sheave ideal for both rope and wire applications as well as a high load version with an ultra strong 2205 stainless steel sheave and 316 stainless steel balls, ideal for high load applications such as halyards, cascading vangs, backstays, outhauls and cunningham systems.
