Triple Block With Becket & Cleat

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.

Installation & Application

Ideal for mainsheet fine-tunes, traveller controls, and high-purchase control systems, the Lewmar Triple Block with Becket & Cleat integrates seamlessly into modern performance cruising and racing deck layouts. Its combination of mechanical advantage, secure holding, and compact efficiency makes it a professional-grade solution backed by Lewmar’s proven deck-hardware expertise.
