Our custom electronics box, UnioBox 66, is made of aluminium extruded sides with top and bottom made of sheet metal. There are a few standard sizes in silver, but most of our customers specify a custom size. We can also make the front panels to match and we can make connector holes at the same time. The custom electronic enclosure end plates are fixed via self tapping screws into screw ports in the side extrusions. It comes in a standard 66mm height.
