Viadana Wind Speed Ball Bearing Double Blocks with Becket and Fixed Head are designed for sailing and marine rigging applications where a two-sheave block with a stable fixed attachment and an additional becket is required. The double-sheave configuration is suitable for multi-part rope systems, while the becket provides an extra attachment point for the standing end of the line.

The blocks are manufactured from 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 trimming and repeated load changes. The fixed head keeps the block orientation stable within the rigging arrangement.

Three sizes are available for ropes up to 8, 10 and 12 mm, with corresponding sheave diameters of 34, 45 and 56 mm. Breaking loads range from 800 to 1450 kg and working loads from 300 to 580 kg.
