Schaefer’s 7 Series Blocks offer medium sized cruising and racing yachts Delrinâ„¢ and Delrinâ„¢ Ball Bearing sheave Blocks with a stunning combination of strength and performance.
Available with highly polished Stainless Steel or Black Hardcoat Anodized Aluminum cheeks that are reinforced with large Stainless Steel V-Straps and head posts. This robust yet lightweight construction produces an exceptionally strong block built to perform well past other plastic designs. We use only the toughest, high-impact material available so you’ll be sailing while others are fixing failed gear.
All of our 7 Series Blocks work with convenient Universal Adapters and contain our three-way head that allows for free swiveling or front/side set positions.
