Discover the Power of Precision in Every Turn

Imagine slicing through choppy waters during a regatta, your sheets running smooth and responsive under maximum strain. That's the reality with the Lewmar 60mm HTX single block. Crafted from years of sailor feedback and engineering prowess, this block stands out in demanding setups where every ounce of efficiency counts. Sailors rave about its ability to handle modern, low-diameter lines without flinching, making it a go-to for performance-oriented rigging.

Unlike bulkier alternatives, the HTX series keeps things lightweight at just 7.5 ounces while delivering a robust 2422-pound working load limit. It's not just hardware—it's a seamless extension of your boat's control systems, perfect for those moments when split-second adjustments define the race or passage.

Engineered Features That Outperform

The secret to the HTX's reliability lies in thoughtful design details honed from racing pedigrees. Strong aluminum side cheeks provide unyielding structural integrity, resisting the twist and torque of high-load scenarios. At the heart, a central plain bearing ensures peak efficiency even when loads peak, minimizing friction and heat buildup during prolonged use.

• Side Thrust Delrin Ball Bearings: These keep the sheave aligned perfectly, preventing wear and ensuring ultra-smooth line flow—crucial for 12mm lines zipping through at speed.
• Swivel Head with Grub Screw Lock: Borrowed from Lewmar's elite racing range, this allows 360-degree freedom while locking securely in place, adapting to any sheeting angle without tools mid-sail.
• Swivel Shackle Mount: Effortless installation on padeyes, travelers, or toe rails, with a black anodized finish that shrugs off saltwater corrosion.

Backed by a limited three-year warranty, peace of mind comes standard, reflecting Lewmar's commitment to marine-grade durability.

Technical Specs at a Glance

Built for precision, here's what powers this 60mm sheave single block:

Non-ratcheting design means versatility across any direction, ideal for dynamic loads without a becket or cleat to complicate things.

Perfect Applications for Serious Sailors

This block shines in frequently adjusted systems craving reliability. Think mainsheets on sportboats, outhaul cars, or vang tackles where high loads meet rapid tweaks. Its compatibility with reduced-diameter Dyneema or Spectra lines unlocks lower windage and faster handling—advantages that translate to better boat speed and control.

Cruisers appreciate its low maintenance, while racers love the racing-inspired head that stays put under pressure. Pair multiples for purchase systems, and you've got a setup that rivals pro teams without the custom price tag.

Tips for Long-Lasting Performance

To maximize lifespan, rinse with fresh water after every sail to clear salt crystals. Inspect bearings annually for smooth rotation, and avoid exceeding the safe working load—it's engineered for peaks, not abuse. The anodized aluminum laughs at UV exposure, but a quick polish keeps it looking race-ready.

Pro tip: In high-vibe environments like runners or spinnaker sheets, the Delrin bearings dampen noise, letting you focus on trim rather than clatter.
