A new type of Clewblock has been added to the Rutgerson Clewblock assortment. This new model has an installed clamcleat on the side of the clewblock, which erases the need to install a cleat on the sail.
Without this model, it is necessary to sew on a cleat on the sail in order to fasten the leech line. But now, that step of the sail making process is removed and it is also easier to reach the cleat on the clewblock because it is located closer to the boom.
