50 mm HTX Block - Swivel, Becket

Lewmar 50 mm HTX Block - Swivel, Becket

Years of design and manufacturing experience combined with collaboration with boat builders, designers, and sailors have resulted in the Lewmar HTX Hardware Range. Drawing upon the design of the Racing Range, the HTX blocks are constructed simply from high-quality materials, providing enhanced reliability and consistent performance. These blocks are ideal for frequently adjusted, highly loaded systems that use modern line technology and reduced line diameters, including applications such as halyards, mainsheets, mast bases, and boom vangs.

The 50 mm HTX Block with Swivel and Becket features a central plain bearing that guarantees peak operational efficiency even when subjected to substantial loads, allowing smooth and consistent performance in high-demand sailing scenarios. Side thrust Delrin ball bearings minimize friction and enhance overall functionality, while robust aluminium side cheeks provide maximum strength and resilience to withstand demanding sailing conditions. The swivel head design is inspired by Lewmar's acclaimed Racing Range and incorporates a grub screw locking mechanism to ensure components remain securely in place regardless of conditions. An integrated becket adds versatility for purchase system rigging applications.

With a safe working load of 800 kg (1,762 lbs), a breaking load of 1,600 kg (3,524 lbs), and a maximum line size of 10 mm (3/8"), this block is well suited to modern performance sailing rigs. Weighing just 150 g (5.3 oz), it adds minimal weight while delivering the strength and reliability demanded by serious sailors.
