NTR Double Control Line Sheaves

Smooth, Balanced Control Line Management

The Lewmar Double Control Line Sheaves are designed to deliver efficient, low-friction handling of control lines within Lewmar track, traveller, and sail-handling systems. By providing a dedicated dual-sheave solution, they support balanced load distribution and precise line control where smooth operation and reliability are essential.

Dual-Sheave Functionality

Featuring two precision-engineered sheaves in a compact assembly, the Double Control Line Sheaves allow opposing control lines to be led cleanly and symmetrically. This configuration minuses friction and uneven loading, ensuring consistent response when trimming or easing under load. The result is improved feel and accuracy at the control position, particularly in high-load or frequently adjusted systems.

Marine-Gade Construction

Manufactured from durable, marine-grade materials, the Lewmar Double Control Line Sheaves are built to withstand sustained tension, repeated cycles, and exposure to harsh marine conditions. Corrosion-resistant components and robust construction ensure long-term performance and dependable operation in both cruising and performance sailing environments.

Low-Friction, Dependable Performance

The precisely profiled sheaves promote smooth rope flow and efficient load transfer, reducing wear on control lines and associated hardware. By lowering friction and preventing rope twist or chafe, the sheaves contribute to improved system efficiency and extended service life of running rigging.

System Integration & Application

Designed for seamless compatibility with Lewmar traveller end stops, control tracks, and related sail-handling hardware, the Double Control Line Sheaves integrate cleanly into new installations and professional refits. Ideal for mainsheet traveller systems and other control applications, they provide a refined, system-led solution backed by Lewmar’s long-standing expertise in performance deck hardware.
