HARKEN Mid-Range Blocks

Great for mainsheet or spinnaker blocks and control lines on offshore yachts. Robust construction handles high loads. Ball-bearing sheaves minimize friction. Beefier posts and wrap-around straps create much higher working loads. Three-way head system permits blocks to swivel or be fixed side-to-side or fore-and-aft. Beckets are removable. Where applicable, blocks use 1/4" fasteners.

  • Sheave: Delrin except for aluminum 1542 wire block
  • Ball Bearings: Torlon high-load ball bearings in fitted races
  • Sheave Size: 3" (76mm)
  • Line Diameter: 9/16" max.
  • Cheek Material/Finish: Plastic with wrap-around stainless straps
  • Shackle/Strap Type: Three-way head locks in two orientations or swivels; heavy-duty screw pin shackle
