LEWMAR Control Single Stand Up Block
The Lewmar Control Single Stand-Up Block is engineered to improve the efficiency and usability of control lines by keeping them correctly presented and easy to engage. Purpose-designed for modern deck layouts, this marine-grade hardware delivers professional-grade performance backed by Lewmar's proven expertise.
Key Features
- Spring-loaded stand-up mechanism automatically supports the sheave in an upright position when lines are slack, improving line pickup and reducing the risk of lines dropping flat on deck
- High-strength, glass-filled sheave handles heavy loads with reliability
- Stainless steel ball bearings and grooves withstand saltwater exposure and maintain peak performance without deformation
- Marine-grade construction engineered for durability and long-term reliability under repeated use and exposure to UV
- Open design allows sand and salt to be effortlessly flushed out for easy maintenance
- Smooth, low-friction operation reduces handling effort and wear and tear
- Lightweight design perfect for hand-held applications
Ideal for control lines, mainsheets for dinghies and keelboats, spinnaker sheets, barberhaulers, and Genoa sheets. Well-suited to both new builds and professional refits with a compact footprint and practical functionality.
