5 Series Blocks - 51mm Sheave

Stainless Steel

Schaefer 5 Series Blocks offer small-to-medium-sized cruising and racing yachts an extremely high strength-to-weight ratio, resulting in a highly refined and reliable block. Their strength and styling has also made them popular for medium use on bigger yachts, when combined with Schaefer larger series blocks.

Schaefer's versatile Universal Head design has a 3-way built-in locking feature and accepts "universal" adapters for custom mounting. Blocks are made of tumbled and polished stainless steel cheeks with UV-protected Delrin® sheaves to withstand the elements and potential mishaps.
