Complete Your Purchase

Harken 76mm Midrange Double Block with Becket allows either a 2:1 or 3:1 purchase. 

Great for mainsheet or spinnaker blocks and control lines on offshore yachts. Robust construction handles high loads offshore. 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.
