Lewmar 50mm HTX Single Block with Swivel Head and Fiddle

Lewmar 50mm HTX Single Block with Swivel Head and Fiddle

The Lewmar HTX Single Block with Swivel Head and Fiddle delivers increased mechanical advantage in a compact, high-strength design. The fiddle configuration supports efficient load management, while the wivel head self-aligns with changing lead angles to reduce friction and sideloading. Constructed using Lewmar HTX Composite technology, the block offers excellent strength-to-weight performance and smooth, reliable operation under load. Ideal for fine-tune controls and high-performance sailing systems on cruising and racing yachts.

Features:

Compact Power for Control Systems

The Lewmar HTX Single Block with Swivel Head and Fiddle is engineered to deliver efficient load handling and precise control in space-constrained, high-performance sailing applications. Combining mechanical advantage with intelligent alignment, it provides a powerful yet compact solution for modern control systems that demand both strength and finesse.

Fiddle Configuration for Increased Purchase

The integrated fiddle arrangement delivers enhanced mechanical advantage within a minimal footprint, allowing significant loads to be managed with reduced effort. This configuration is ideal for trimming, fine-tuning, and cascading control systems where progressive adjustment and consistent load management are essential to accurate sail control.

Self-Aligning Swivel Head

Fitted with a smooth-running swivel head, the block automatically aligns with changing lead angles as loads shift across the system. This self-orienting design reduces sideloading and friction, ensuring efficient rope flow while protecting both rope and hardware from uneven wear in dynamic sailing conditions.

HTX High-Strength Construction

Manufactured using Lewmar’s advanced HTX composite technology, the block offers an exceptional strength-to-weight ratio. Reinforced composite cheeks and precision-engineered sheaves are designed to withstand high working loads while minimising flex, friction, and long-term wear, delivering reliable performance in demanding deck environments.

Smooth, Dependable Performance

Optimised sheave geometry ensures smooth, low-friction rope movement under load, supporting responsive trimming and controlled easing. Even load distribution across the fiddle configuration contributes to reduced handling effort, improved feedback, and consistent performance over extended sailing periods.
