The Middle Atlantic DECP-1X4 is a 1RU panel that allows you to mount any four low-voltage Decora devices directly onto the rackrail of a standard 19" enclosure. Panels accommodate as many as four devices including the RPS Series remote power switch and the TEMP-DEC temperature display. It is constructed from one-piece of flanged steel (with an open area of 1.62" between flanges) and has a black powder coat finish.
