TB Car With Shackle & 1 Pair CL Sheaves

Reliable Traveller Control for High-Load Systems

The Lewmar TB Car with Shackle & 1 Pair Control Line Sheaves is engineered to provide strong, precise traveller operation in demanding sailing environments. Designed for cruising yachts and performance applications alike, it offers dependable load handling and efficient control-line management where smooth, accurate sail trim is essential.

Track-Bearing (TB) Car Design

The Track-Bearing (TB) configuration is optimised to transmits movement under tension. This design delivers consistent low-friction travel, reducing binding and ensuring responsive control during trimming and easing in high-load mainsheet systems.

Integrated Shackle Attachment

A robust marine-grade shackle provides a secure and versatile connection point for mainsheet blocks or purchase systems. This direct mechanical interface ensures efficient load transfer while allowing flexibility in rig configuration to suit a wide range of sail plans and deck layouts. 

Single Pair of Control Line Sheaves

The integrated pair of control line sheaves enables smooth, low-friction routing of traveller control lines. This balanced arrangement supports efficient trimming from both sides of the track, improving handling feel, reducing effort at the control position, and minimising wear on running rigging during frequent adjustment.

Smooth, Consistent Performance

Precision-engineered bearing surfaces and sheave geometry ensure dependable, low-resistance movement along the track. This smooth operation enhances sail-shape control, supports accurate traveller positioning, and contributes to extended service life of both car and track components.

Marine-Grade Construction

Manufactured from high-strength, corrosion-resistant marine-grade materials, the Lewmar TB Car with Shackle & 1 Pair CL Sheaves is built to withstand sustained loads, shock forces, and continuous use. Its durable construction ensures long-term reliability in both coastal cruising and offshore sailing conditions.

System Integration & Application

Designed for seamless compatibility with Lewmar traveller track systems, this TB car is suitable for new installations and professional refits. Commonly specified for mainsheet traveller systems, it delivers a clean, system-led solution where strength, control efficiency, and reliability are essential, backed by Lewmar’s long-standing expertise in high-load sail-handling hardware.
