Lewmar 50 mm synchro blocks are engineered for speed, efficiency and superior handling. These blocks suit a range of purposes from performance cruising
yachts to specific high-load low-movement applications on racing sailboats. Lewmar uses a combination of scientifically optimised
block geometry, a Free-Spin bearing and self-aligning head to reduce friction and increase efficiency by up to 40% over budget
blocks on mainsheet systems.
Each component is perfectly synchronised with the movement of the rope, providing you with an easier, smoother transfer of power
from deck to sail and less wear on your rope.
Synchro Block Features:
Stainless steel strap for improved strength and longer service life
Stiff glass fibre reinforced cheeks to prevent lines from wedging
Innovative design with "tool-free" sliding swivel locking mechanism
Synchro Block Applications:
Plain bearing blocks are typically used for heavy and static loads in:
