Sheave runs exclusively on a ball-bearing system for fast trim and release.
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. A three-way head system permits blocks to swivel or be fixed side-to-side or fore-and-aft. The beckets are removable. Where applicable, blocks use 1/4" fasteners.
