The GMG-02 rubber heating mat is a device to use outdoor and indoor in places where spot heating is required, e.g. at unheated work stations. The mat is made of thick, low-temperature-resistant rubber, from which power cords with „male” and „female” sockets are led. This enables the electrical connection of several mats, which can be powered by one 230 V AC point. GMG-02 mats have been designed to use on stair landings and other places in circulation routes exposed to icing. It is possible to connect 4 mats via cables with sockets to one power supply point.
