HARKEN 76mm Midrange Single Block, Aluminum Sheave, 1542
The Harken 76mm Midrange Single Block 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. 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.
