Viadana Wind Speed Ball Bearing Triple Blocks with Fixed Head for Rope up to 8-12 mm, 34-56 mm Sheaves - Osculati 55.084.08 / 55.084.10 / 55.084.12

Viadana Wind Speed Ball Bearing Triple Blocks with Fixed Head are designed for sailing and marine rigging systems where a three-sheave block is required for multi-part rope arrangements. The triple-sheave configuration allows several rope passes to be incorporated into a compact assembly, while the fixed head keeps the block in a stable orientation within the rigging system.

The blocks are made of reinforced black nylon and incorporate stainless steel components for durable marine use. Their sheaves run on ball bearings to support smooth rope movement and efficient operation during repeated trimming and load changes. The range is available in three sizes, allowing the block to be matched to different rope diameters and load requirements.

The 8 mm version uses 34 mm sheaves, the 10 mm version uses 45 mm sheaves and the 12 mm version uses 56 mm sheaves. Breaking loads range from 800 to 1450 kg, while working loads range from 300 to 580 kg. Viadana articles 89.63, 90.64 and 91.61 correspond to Osculati codes 55.084.08, 55.084.10 and 55.084.12 respectively.
