Synchro Triple Block with Swivel Head

Dynamic Multi-Line Control 

The Lewmar Synchro Block Triple Swivel Head is engineered to deliver smooth, efficient management of multiple loaded lines in performance sailing environments. Designed for applications where dynamic alignment and precise control are essential, it provides a refined solution for complex trimming systems that demand reliability under load.

Articulated Triple Swivel Design

Featuring a triple swivel head, the Synchro Block automatically aligns with changing line angles, reducing side-loading and unnecessary friction throughout the control system. This articulated movement ensures consistent rope flow regardless of lead direction, enhancing trimming efficiency while minimising wear on both rope and hardware.

Synchro Series Engineering

Developed as part of Lewmar’s proven Synchro range, the block combines advanced bearing technology with carefully profiled sheaves to deliver low-friction performance under load. The tri-sheave configuration enables effective load sharing and compact multi-purchase layouts, making it ideal for control cascades, mainsheet systems, and high-load running rigging.

Smooth, Reliable Performance

Engineered for dependable operation in demanding conditions, the Synchro Block Triple Swivel Head delivers predictable, responsive line handling with minimal resistance. The self-aligning head reduces shock loads and promotes smooth trimming and easing, supporting confident sail control during manoeuvres and sustained sailing. 

Installation & Application

Designed for integration modern deck and rigging layouts, the Lewmar Synchro Block Triple Swivel Head is well suited to performance cruising and racing yachts alike. Its flexible alignment and load-handling capability make it an effective solution for systems requiring accuracy, durability, and professional-grade performance, all backed by Lewmar’s long-standing deck-hardware expertise.
