Schaefer Aluminum Fiddle Block with Cam and Becket allows for 3:1 or 4:1 tackles on boom vangs and mainsheets.
Universal head allows one block to function as a front shackle, side shackle, or swivel shackle block. Large sheave diameters and high working loads make them suitable for sheet and control blocks on medium to large offshore boats. Beckets are removable. 704 series are aluminum; 705 blocks are stainless. Where applicable, blocks use 1/4" fasteners.
7 Series Fiddle Blocks are constructed with a large Ø single sheave and dual in-line sheaves with the ability to spread oversized lines 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 configuration prevents sheets from crossing and chafing and distributes load to three axles instead of the two seen in other block designs.
Delrin™ or Delrin™ Ball Bearing sheave designs are offered with either high luster Stainless Steel or Hardcoat Anodized Aluminum cheeks. The 7 Series Fiddle Blocks work with our Universal Adapters. Spread the load and get control of your main.
Cheeks are constructed of tumbled and polished Stainless Steel or Hardcoat Anodized Aluminum for maximum corrosion resistance and strength. Sheaves are made of high-impact Delrin™ or Delrin™ with Delrin™ Ball Bearings.
