Abstract

La présente invention concerne un ensemble de serrage de rail en queue d'aronde modulaire qui comprend un corps ayant un composant de serrage fixe. Un composant de serrage mobile est opposé au composant de serrage fixe. Un élément de fixation par serrage fileté s'étend à travers le composant de serrage mobile et dans le corps pour tirer le composant de serrage mobile en prise avec le corps. Une traverse réversible amovible s'étend transversalement à travers le corps entre le composant de serrage fixe et le composant de serrage mobile dans un canal cannelé. La barre transversale présente à la fois un côté rail universel et un côté rail MIL-STD 1913.
