Harken 10mm Lead Ring

The Harken 10mm Lead Ring (MPN 3270) is a precision line-routing component designed for sailing applications requiring smooth, low-friction performance with minimal adjustment capability. Constructed from hard-anodized 6061-T6 aluminum, this lead ring delivers a slippery surface finish that reduces wear on rigging line while maintaining structural integrity under load. The 10mm center hole accommodates standard sailing hardware, while the 6mm outer groove width provides controlled line routing without snagging or binding.

Harken's hard-anodized aluminum construction eliminates moving parts, which translates directly to extended service life and predictable, maintenance-free operation in salt-air environments. The 10mm lead ring weighs just 0.3 lbs, making it an ideal weight-saving choice for racing and cruising applications where rigging efficiency matters. The smooth anodized surface allows line to flow freely without friction-induced wear, a critical advantage on jib in-haulers, twings, barberhaulers, lazy jacks, and cascading backstay systems where fine-tune adjustments are rare.

This lead ring serves sailors and riggers who prioritize durability and simplicity over complex mechanical solutions. Its compact 2 x 1 x 4-inch footprint allows straightforward integration into existing rigging layouts without requiring significant hardware modifications. The no-moving-parts design appeals to operators seeking corrosion-resistant, long-term reliability in offshore, coastal, and freshwater applications where replacement cycles are minimized and performance consistency is essential.

Harken's heritage in precision sailing hardware ensures this lead ring meets the exacting standards of both professional riggers and serious recreational sailors. The 10mm configuration is a proven standard in the industry, widely compatible with contemporary rigging systems and proven across thousands of installations in demanding marine environments.
