Rail
Mount System (RMS)
SPS has developed a Rail Mount System to accommodate all sizes
of instruments and electronics for internal mounting in our RTM
boxes. The rail system has four rails and has been designed to have
one set of rails stationary across the box while the other two rails
slide on the stationary rails. The rails are manufactured using
carbon steel and have a galvanized finish. Each RTM box comes with
a different set of rails as shown below. SPS's RMS is
combined with Corner Mounts to transfer the weight of all internal
instrumentation components to the enclosure exterior mounting hardware.
This internal/external mounting combination eliminates stress on
the enclosure.
