Schaefer's 8 Series Stainless Blocks add strength and brilliance to your deck. Featuring Delrin™ sheaves, forged stainless steel D shackles, bolted construction for strength and Stainless Steel cheeks polished to a high luster add beauty and confidence to your boat.
Manufacturer part #: 704-51
7 Series Fiddle Blocks are constructed with a large Ø 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 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.
Use for:
Mainsheet Systems boats to 34' (10.3 m)
Halyard Leads boats to 34' (10.3 m)
Genoa Leads boats to 34' (10.3 m)
