L'<strong>anneau en D inox droit 50 mm soud\u00e9<\/strong> (804010) est enti\u00e8rement soud\u00e9, sans ouverture : la soudure ferme l'anneau et emp\u00eache le doigt du mousqueton de se placer en position ouverte sous l'anneau. L'<strong>anneau en D inox droit 50 mm ouvert<\/strong> (804009) pr\u00e9sente une ouverture \u00e0 la base, qui permet de l'enfiler sur la sangle sans avoir \u00e0 la d\u00e9filer \u2014 on l'utilise lorsqu'il faut ajouter un anneau \u00e0 un harnais d\u00e9j\u00e0 mont\u00e9, sans le d\u00e9monter.

Si vous montez un harnais neuf, utilisez les soud\u00e9s.
