Lewmar 105mm Runner Block
Lewmar 105mm Runner Block
The Lewmar Runner Block is designed to handle the high, dynamic loads generated in running backstay and rig-control systems. Engineered for smooth, controlled operation under tension, it supports precise adjustment and reliable mast support in demanding sailing conditions. Manufactured from durable, marine-grade materials, the block offers ow-friction performance and long-term reliability. Ideal for runners and checkstays o performance cruising and racing yachts where strength and confidence are essential.
Features:
The Lewmar Runner Block is engineered to manage the extreme and highly dynamic loads generated in modern running backstay and rig-control systems. Designed for performance cruising and racing yachts alike, it provides dependable, precise load handling where rig integrity and responsive control are critical to sailing performance and safety.
Optimised Runner Geometry
Specifically developed for runner and backstay applications, the block’s geometry ensures clean, predictable alignment under load. This optimised design supports efficient force transmission through the rig, helping maintain consistent mast support while allowing accurate adjustment during sail changes, manoeuvres, and varying wind conditions.
Heavy-Duty Marine Construction
Manufactured from high-strength, marine-grade materials and engineered to withstand sustained tension and shock loading, the Lewmar Runner Block is built for longevity in demanding offshore environments. Robust side plates, a high-load sheave assembly, and precision tolerances deliver exceptional structural integrity and resistance to wear under repeated high-cycle use.
Smooth, Controlled Performance
Designed to minimise friction even under extreme loads, the block delivers smooth rope movement and predictable response during loading and easing. This controlled performance reduces peak stress on running rigging and hardware, helping protect rope, fittings, and the rig as a whole while improving trimming accuracy and crew confidence.
