This system is an innovative new solution for protecting cables from damage and preventing trips by pedestrians and employees. The pieces articulate left and right, allowing the system to turn corners and adapt to the layout of the room. The modular design makes it easy to reconfigure, repair, and replace targeted segments - even while the cable remains connected. The system can be customized to any length and no tools are required for assembly. The internal channel opening is 3/8"H X 3/4"W.
