Hayn Marine Stemball and Open Body

Stemball and Open Body

The stemball's spherical head seats into a compatible cup fitting at the chainplate or deck fitting, allowing the wire end to move freely through its working arc without bending stress concentrating at the terminal interface — the primary mechanism behind long-term fatigue failure in standing rigging. The chromed bronze open body provides direct visual access to thread engagement during tensioning and inspection, and the forged bronze construction prevents galling at the threaded interface.
