Rutgerson’s Clewblocks have a 60mm, 80mm or 100mm removable acetal sheave and are available in both silver and black anodized cheek plates. The webbing slots are smoothly rounded in order to prevent chafe for maximum durability, and the appliance angles of the slots have been improved to better line up with the aspect ratio of the sail.
The sheave can easily be removed by unscrewing the M5 bolt that assembles the construction through a SS socket.
