Harken 76mm Midrange Fiddle Block handles high loads found with main sheets and boom vangs.
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.
