  • Integrated Design

    Integrated Design

    The specially formed high-strength architectural shape of the Impasse rail is contoured to carry anti-ram steel cable and/or detection equipment. This helps you consolidate your physical security protection into a single perimeter solution.

    Impasse rail as raceway for wiring Intrusion Detection Systems (IDS): Use the Impasse rail to covertly secure IDS to the security fence.

    The Impasse rail can also easily integrate any intrusion detection sensor. The distinctively shaped Impasse rail conceals IDS cables to delay, deny, deter and detect intruders. Also, the rail features a secure IDS attachment to help keep the sensor cables in place and minimize the number of false alarms. So you can rest assured the Impasse rail will increase the probability of detection.


    Impasse rail as raceway for wiring Conduits: Use the Stalwart's Impasse rail as a conduit tray for electrical conduits. The high cost associated with securing an asset are often overlooked until the last minute. Some of the items used in modern perimeter security systems include lighting, access control wiring, intrusion detection sensor wiring, CCTV cables, communication fiber and electrical wiring.

    As an added benefit, the Impasse rail can house all the components needed to install a perimeter security system. This allows for quicker installation and minimized construction cost from not having to incur the cost of trenching or boring.


    Impasse rail as raceway for wiring. Video and Communications Wiring Use the Impasse rail to carry communication cables along the perimeter.

    The Impasse rail delivers added value with its ability to also incorporate wiring for video, CCTV and other communications. When video and communication systems are installed the probability of detection is higher.


    Impasse Rail with Access Control Access Control Wiring Use the Impasse rail to carry communication cables along the perimeter.

    Access control is a key factor in perimeter security systems. Take advantage of the Impasse rail to carry access control wiring from one entry control point to the next and avoid the burdensome cost of a patchwork design using trenching and boring.


    Impasse with Anti-Ram Barrier Anti-Ram Cable Conceal crash barrier components easily with the Impasse rail.

    The Impasse rail is specially designed to incorporate the cable of the Stalwart anti-ram barrier system.
