Viadana Wind Speed Ball Bearing Double Fiddle Blocks with Swivel Head for Rope up to 8-12 mm, 34-56 mm Sheaves - Osculati 55.079.08 / 55.079.10 / 55.079.12

Viadana Wind Speed Ball Bearing Double Fiddle Blocks with Swivel Head are designed for sailing and marine rigging systems that require a two-sheave fiddle block configuration for multi-part rope arrangements. The fiddle layout provides a compact way to route several rope passes through the block, while the swivel head allows the block to align with the direction of the applied load.

The blocks belong to the Wind Speed ball-bearing range and combine reinforced black nylon construction with stainless steel components. Both sheaves operate on ball bearings to provide smooth rope travel and efficient movement during repeated trimming and adjustment. The range is available in three sizes for ropes up to 8, 10 and 12 mm.

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, with working loads from 300 to 580 kg. The corresponding Viadana articles are 89.56, 90.56 and 91.53, matched with Osculati codes 55.079.08, 55.079.10 and 55.079.12 respectively.
