Rutgerson’s Clewblocks have a 60mm, 80mm or 100mm removable acetal sheave and are available in 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.
*Please note that these are general recommendations, based on monohull standard boats cruising during average weather conditions. Selection of the appropriate product by the buyer shall rest solely with the buyer and Rutgerson accepts no responsibility for any such selection.
