The type of enclosure (freestanding, wall-mounted, server, or IP66 outdoor) should be determined based on the size of the devices to be mounted within. In most cases, standard sizes from mass-produced products meet the requirements. In other cases, custom enclosures can be produced. Considering the type of devices to be mounted in the rack enclosure, accessories such as a 19" socket, organizer, light fixture, and closing panels are considered.
