7 Series Fiddle Blocks - 60mm Sheave
Stainless Steel
Schaefer 7 Series Fiddle Blocks are constructed with a large-diameter single sheave and dual in-line sheaves to spread oversized line over a greater surface. This high-load design withstands shock loads associated with mainsheet and boom vang systems. The powerful configuration prevents sheets from crossing and chafing, and it distributes load to three axles, instead of the two seen in other block designs.
Schaefer's universal head design has a 3-way built-in locking feature and accepts their universal adapters for custom mounting. Blocks are made of tumbled and polished, stainless steel cheeks with UV-protected Delrin® sheaves.
