Lewmar 40mm Control Triple Block with Swivel Head
Lewmar 40mm Control Triple Block with Swivel Head
The Lewmar Control Triple Block with Swivel Head provides smooth, efficient load handling for high-purchase control systems. Its compact triple-sheave design increased mechanical advantage, while the swivel head self-aligns with changing lead angles to reduce friction and sideloading. Manufactured from durable, marine-grade materials, the block offers reliable, low-friction performance in demanding onboard environments. Ideal for control cascades and fine-tuning systems on cruising and performance yachts.
Features:
Advanced Multi-Purchase Control
The Lewmar Control Triple Block with Swivel Head is engineered to deliver efficient, precise handling of complex control systems where increased mechanical advantage is required. Designed for modern sailing rigs, it supports high-purchase arrangements that allow loads to be managed smoothly and accurately, enhancing control across demanding trimming and adjustment tasks.
Triple-Sheave Efficiency
Featuring a compact triple-sheave configuration, the block enables significant load reduction within a space-efficient footprint. Even load distribution across the three sheaves improves system efficiency while reducing effort at the line, making it ideally suited to cascades, fine-tune systems, and other control applications requiring incremental adjustment under load.
Swivel Head Alignment
The integrated swivel head allows the block to self-align with changing lead angles, minimising side-loading and unnecessary friction. This adaptive movement ensures consistent rope flow and protects both rope and hardware from uneven wear, particularly in dynamic systems where line direction varies during operation.
Smooth, Consistent Performance
Designed to minimise friction and deliver predictable rope movement, the block provides responsive, controlled operation during trimming and easing. The combination of triple sheaves and a freely rotating swivel head supports refined load management, reduced handling effort, and reliable performance over extended sailing periods.
