The 65LIV RAPID tool, a facilitating instrument for the manual installation of the ART.65LIV “Gancetto Livio” (known as the tutor lock by Vignetinox). It reduces installation times and ensures standardization in the assembly of the Gancetto Livio, improving the retention between the tutor and the supporting wire. The primary cause of the ineffectiveness of the Gancetto Livio’s retention is human error, which compromises its use. This error is completely eliminated thanks to the uniform mechanical action of the RAPID on the Gancetto Livio.
