Schaefer Aluminum Sheaves
Schaefer's Blocks rely on a variety of sheaves designs and scorings. Schaefer sheaves are design to be compatible with Schaefer products. There is a risk of incompatibility or failure when using Schaefer sheaves in blocks manufactued by anyone other than Schaefer Marine. The Schaefer Aluminum Sheave configuration accommodates both line and wire, providing a chafe-free surface for line while giving full support to wire to prevent flattening. Hardcoat Anodized 60601-T6 Aluminum offers superior strength and corrosion resistance.
