3 Series Blocks - 37mm Sheave
Stainless Steel or Aluminum
Schaefer 3 Series Blocks offer strong, high-quality metal construction built to take the punishment associated with running rigging mounted on deck or spars. They are excellent for use on small cruisers, day sailers and high-performance racing dinghies.
Blocks are made with either tough, hardcoat-anodized aluminum cheeks or brilliant, stainless steel cheeks. Both feature UV-protected Delrin® sheaves to withstand the elements and potential mishaps.
