Do you have a need for an enclosure that is durable, weather-proof, and provides easy access to your sensitive electrical equipment and connections, but don’t want the cost or have the space needed for installing a conventional case.  Interrail can provide a solution by offering a variety of types and sizes of junction oxes.  Our junction boxes feature heavy duty aluminum construction which is light enough to allow for easy installation, yet rugged enough to withstand years of use in the field.
