Viadana Wind Speed Ball Bearing Single Footblocks for Rope up to 8-12 mm, 34-56 mm Sheaves - Osculati 55.074.08 / 55.074.10 / 55.074.12

Viadana Wind Speed Ball Bearing Single Footblocks are designed for sailing and marine rigging systems where a compact deck-mounted single block is required to guide and redirect control lines. The footblock configuration allows the block to be installed directly on a suitable mounting surface while maintaining a controlled rope path.

The blocks belong to the Viadana Wind Speed range and combine reinforced black nylon construction with stainless steel components. The sheave runs on ball bearings to provide smooth rope movement and efficient operation during repeated trimming and load changes. Three sizes are available to suit different rope diameters and rigging requirements.

The 8 mm version uses a 34 mm sheave, the 10 mm version uses a 45 mm sheave and the 12 mm version uses a 56 mm sheave. Breaking loads range from 800 to 1450 kg, while working loads range from 300 to 580 kg. Viadana articles 89.65, 90.66 and 91.63 correspond to Osculati codes 55.074.08, 55.074.10 and 55.074.12 respectively.
