Lewmar 40mm Control Block Single Swivel Head
Lewmar 40mm Control Block Single Swivel Head
The Lewmar Control Block Single Swivel Head delivers smooth, efficient handling of control lines with automatic alignment to changing lead angles. The self-orienting swivel head reduces friction and sideloading, ensuring consistent rope flow and precise trimming. Constructed from durable, marine-grade materials, the block offers reliable, low-friction performance in demanding onboard environments. Ideal for control lines, travellers, and fine-tune systems on cruising and racing yachts.
Features:
Precise Line Control
The Lewmar Control Block Single Swivel Head is designed to deliver smooth, accurate handling of control lines where responsiveness and reliability are essential. Ideal for fine-tuning sail trim and managing lightly to moderately loaded lines, it supports confident, precise adjustments across a wide range of sailing applications.
Swivel Head Adaptability
Equipped with a freely rotating swivel head, the block automatically aligns with changing lead angles to reduce sideloading and friction. This self-orienting capability promotes efficient rope flow and consistent control, particularly in dynamic systems where line direction frequently shifts during trimming and manoeuvres.
Durable Marine-Grade Construction
Manufactured from tough, marine-grade materials, the Control Block Single Swivel Head is built to withstand the demands of the onboard environment. Precision-engineered sheave profiles and robust side plates provide dependable strength, resistance to wear, and long-term performance under repeated use.
Smooth, Reliable Performance
Designed to minimise friction and deliver predictable response, the block ensures clean, controlled line movement during rimming and easing. Its compact, stable geometry supports accurate load transfer and responsive sail handling, helping reduce effort and maintain control during extended sailing.
