The Wichard Roller block combines light weight and durable alloy cheeks and sheaves with Delrin needle rollers, to provide a block with both excellent high speed-low load and high-function load characteristics. Roller blocks offer the added advantage of interchangeable head fastening systems, which allow for multiple attachment methods. This feature also provides the ability for your yacht’s systems to be quickly modified / relocated to boat suit your changing requirements and the evolution of yachting control systems.
