We were dissatisfied with what was available for mounting single and multiple rail-mount instruments in the field, so we designed our own. Made of metal with a rugged clear polycarbonate cover, the R-BOX meets standards for enclosing indoor and outdoor electronics approved for use in instrinsically safe and non-incendive areas. It installs quickly and easily on a surface or pipe, or in a panel. Use the R-BOX with our SPA and SPT Site-Programmable Alarms and Transmitters, TRY and SIY PC-Programmable Transmitters, and our complete line of economical ECT Signal Isolators, Converters, Repeaters, and Splitters.
