Lewmar Synchro Blocks combine scientifically optimised block geometry, a Free-Spin bearing and self-aligning head reducing friction and an increasing efficiency by up to 40% over budget blocks on mainsheet systems. With each component perfectly synchronised with the movement of the rope, the result is an easier, smoother transfer of power from deck to sail and less wear on your rope. These plain bearing blocks are typically used for heavy and static loads in halyard tuning, mainsheets systems, mast foot blocks, mast head blocks and boom vangs. The Synchro blocks are equiped with stainless steel straps for inproved strength and a longer service life whilst stiff glass fibre reinforced cheeks prevent lines from wedging. The innovative design has a Tool-Free sliding swivel locking mechanism, a simple switch changes from a swivelling to fixed shackle.
