Lewmar 40mm Triple Block With Becket & Cleat

Lewmar 40mm Triple Block With Becket & Cleat

The Lewmar Triple Block with Becket & Cleat delivers high mechanical advantage and secure line control in a compact, integrated design. Its triple-sheave configuration allows heavy loads to be handled smoothly, while the integrated becket supports clean cascade systems and the cleat enables fast, reliable line locking. Manufactured from durable, marine-grade materials, the block offers smooth, low-friction performance and long-term reliability. Ideal for high-load trimming and fine-tune applications on performance cruising and racing yachts.

Features:

All-In-One Control for High-Load Systems

The Lewmar Triple Block with Becket & Cleat is engineered to deliver maximum mechanical advantage, precise trimming control, and secure line management within a single, compact unit. Designed for demanding sailing applications, it provides an efficient and confidence-inspiring solution where high loads and frequent adjustment are part of everyday sailing.

Triple-Sheave Mechanical Advantage

The three-sheave configuration delivers significant purchase, allowing heavy loads to be handled with reduced effort and trimming accuracy. Even load distribution across the sheaves enhances system efficiency and responsiveness, making the block well suited to fine-tune systems, control cascades and other applications where incremental adjustment is critical.

Positive Cleat Control

Fitted with an integrated cleat; the block allows lines to be locked off quickly and securely once trimmed. This positive holding capability enables precise adjustments to be maintained under load without reliance on secondary hardware, improving ergonomics and operational confidence at the trimming position.

Marine-Grade Construction

Manufactured from durable, marine-grade materials and precision-engineered for sustained loads, the Lewmar Triple Block with Becket & Cleat is built to withstand the rigours of the marine environment. Robust side plates and carefully profiled sheaves deliver long-term strength, wear resistance, and reliable performance in demanding offshore and performance sailing conditions.

Smooth, Reliable Performance

Optimised sheave geometry minimises friction during trimming and easing, providing smooth, predictable rope movement even under high tension. Reduced energy loss improves handling efficiency and helps protect running rigging from unnecessary wear over extended sailing programmes.
