Lewmar Blocks - Synchro Triple + Becket + Cam 420312
Triple + Becket + Cam
Designed and engineered for speed, efficiency and superior handling, the Synchro range of blocks combine a free spin bearing with a self aligning head to reduce friction and increase efficiency. Each component is designed to perfectly synchronise with the movement of the rope to provide smooth and efficient transfer of power with reduced rope wear.
A lockable head allows for in-line or 90° positioning while the integrated 30° floating movement provides improved alignment. Additionally, the head may be left to freely rotate when in the unlocked position.
