Viadana Wind Speed Ball Bearing Triple Blocks with Becket and Fixed Head for Rope up to 8-12 mm - Osculati 55.085.10 / 55.085.12

Viadana Wind Speed Ball Bearing Triple Blocks with Becket and Fixed Head are designed for sailing and marine rigging systems requiring a compact three-sheave arrangement with an additional becket attachment point. This configuration is suitable for multi-part rope systems where several rope passes and an attachment point for the standing end of the line are required.

The blocks belong to the Viadana Wind Speed range and combine reinforced black nylon construction with stainless steel components. The sheaves operate on ball bearings to support smooth rope movement during trimming and repeated load changes, while the fixed-head design keeps the block in a stable orientation within the rigging system.

The range covers rope capacities from 8 to 12 mm. Available models include Viadana article 89.64 for the 8 mm configuration and Viadana article 91.62 for the 12 mm configuration. Osculati versions include 55.085.10 for ropes up to 10 mm with a 45 mm sheave and 55.085.12 for ropes up to 12 mm with a 56 mm sheave.
