Lewmar HTX Block Single

Lewmar HTX Block Single

Product Description

The Lewmar HTX Block Single is part of the innovative HTX Hardware Range, developed through years of collaboration with boat builders, designers, and sailors. The range combines advanced materials and design elements to deliver high-performance solutions for modern sailing systems.

Drawing inspiration from Lewmar’s Racing Range, these blocks are crafted with precision and built to withstand the rigors of high-load applications. The blocks are designed for use with modern line technology and reduced line diameters, providing sailors with an efficient solution for frequently adjusted systems. With sizes ranging from 50mm to 90mm in diameter, each block is designed to maximize reliability and functionality.

The HTX Block Single (Diameter 50) is constructed from high-quality materials to ensure long-lasting performance under demanding conditions, making it an ideal choice for lighter, lower-load systems. For the 60mm version, the block is optimized for highly loaded systems that require frequent adjustments, while the 72mm version incorporates strong aluminium side cheeks and a central plain bearing for improved load efficiency. The 90mm block is equipped with side thrust Delrin ball bearings and features a head design inspired by Lewmar's Racing Range, complete with a grub screw swivel head locking mechanism for added security.

Features

• High-Quality Materials: Crafted with robust materials, including aluminium side cheeks and Delrin ball bearings, for enhanced reliability and performance.
• Plain Bearings: Central plain bearing system for smooth operation even under heavy loads.
• Durability: Designed to withstand the harsh conditions of marine environments, providing long-lasting performance.
• Efficient Performance: Optimized sheave size, bearing system, and pin dimensions ensure smooth handling and reduced friction for increased efficiency.
• Grub Screw Swivel Head Locking Mechanism (for 90mm): Ensures secure operation and prevents accidental release of the block in demanding sailing conditions.

Applications

The Lewmar HTX Block Single is ideal for a range of sailing applications, including:

• Modern Line Technology: Perfect for use with modern, reduced-diameter lines for high-load systems.
• Highly Loaded Systems: Suitable for systems that require frequent adjustments under load, such as mainsheets and genoa sheets.
• Racing and Cruising: Whether for racing yachts or cruising boats, the HTX Block delivers the performance needed for demanding applications.
