Lewmar Synchro 72 triple

Lewmar Synchro blocks are designed for fast, efficient and superior line handling. We use a combination of scientifically optimised block geometry, a free-spinning bearing and self-aligning head to reduce friction and increase efficiency by up to 40% compared to budget mainsheet system blocks. This means that each component is perfectly synchronised with the movement of the line, resulting in a lighter and smoother power transfer from deck to sail and less wear on the line. Stainless steel band for maximum strength and longer life. Rigid, fiberglass-reinforced sides prevent the line from snagging. Groundbreaking design with “tool-free” locking mechanism on the swivel. Convenient conversion from swivel to fixed shackle. Plain bearing blocks are often used for large and static loads: halyard adjustment, mainsheet systems, mast foot blocks, mast top blocks and kick. The head can be rotated for straight use straight or 90 degrees, or left freely rotating. Locked shackle bolt can be rotated 30 degrees for better alignment of the block.
