Introduction

The Series 55 Rail System is designed to provide a premium, discrete and easy to install base in any vehicle and for every adventure. The rails have been engineered from aircraft grade aluminum that allow you to mount and position one or more Series 55 20mm trackballs. The mounting pack contains all that you need to mount the rail and be ready to install arms and holders (sold separately).

     

    The Rail

    • Made from matte black anodized aircraft-grade aluminum.
    • Allows top down mounting into surfaces with a minimal footprint.

    The Mounting Packs (Included)

    The mounting packs are specific to the Series 55 rail system and can only be purchased at the time of ordering the rail. The patent pending system allows you to mount to a surface from the top down using the included rivnuts/nutserts when no access below the surface is possible or convenient.
