HTX Upstand Kit for Blocks

Improved Line Presentation at Deck Level

The Lewmar HTX Upstand Kit for Blocks is designed to enhance line handling efficiency by raising compatible HTX blocks off the deck, improving rope lead and accessibility. Engineered for performance-focused sailing systems, it ensures control lines remain correctly presented, even when unloaded, supporting faster, more confident sail handling.

Purpose-Designed Upstand Function

By elevating the block above the mounting surface, the upstand kit helps maintain optimal lead angles into clutches, cam cleats, or winches. This reduces friction, minimises chafe, and improves overall system efficiency, particularly in high-workload areas where quick, reliable engagement of control lines is critical.

HTX High-Strength Construction

Manufactured using Lewmar’s advanced HTX composite technology, the Upstand Kit delivers excellent strength-to-wait performance without introducing unnecessary mass. Its reinforced construction is designed to withstand sustained loads, shock forces, and harsh marine conditions, ensuring long-term durability and dependable performance on deck.

Consistent, Reliable Performance

The stable upstanding support keeps he block correctly oriented, helping prevent lines from dropping flat on deck when slack. This contributes to smoother trimming, reduced handling effort, and improved ergonomics at the control position, an important advantage during manoeuvres or frequent sail adjustments.

Installation & Application

Designed for use with compatible Lewmar HTX blocks, the HTX Upstand Kit integrates seamlessly into modern performance cruising and racing deck layouts. Suitable for new builds and high-quality refits, it provides a clean, professional solution for optimising deck hardware performance, backed by Lewmar’s proven deck-hardware experience.
