Schaefer blocks have been manufactured in the United States since 1966 and are known for their legendary strength. Blocks are made from 316 stainless steel and hard coat anodized 6061-T6 aluminum alloy while the sheaves are made of UV protected Delrin. Schaefer offers the widest range of products for building block and tackle systems. 7 series fiddle blocks are constructed with a large diameter single sheave and dual in-line sheaves with the ability to spread oversized line over a greater surface. This high load design offers the ability to withstand the shock loads associated with Mainsheet and Boom Vang systems. This powerful combination prevents sheets from crossing and chafing and distributes load to three axles instead of the two seen in other block designs.
