Schaefer Single Stainless Steel Block with Becket allows either a 2:1 or 3:1 purchase.
Used extensively for sheet blocks on small- to mid-sized keelboats, and as control line blocks for larger offshore boats. Suitable as mast-base or lead blocks on small- to mid-sized boats. Adaptable universal three-way head. Black anodized aluminum or stainless steel cheeks. Stainless steel straps and posts.
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 teaming up with larger series blocks. The versatile universal head design has a three-way built-in locking feature and accepts "universal" adapters for custom mounting. This block is stainless steel with UV-protected Delrin™ sheaves.
