A wall mount enclosure is a great item when you have a limited space application, making a full size cabinet enclosure impractical. The wall mount elevates the enclosure, freeing up valuable floor space. The enclosed nature offers more security than an open-frame option. As these enclosures are much smaller than floor cabinets, they can't house as many components.
There are many wall enclosure choices with standard 19” rackmount space for components. They range quite broadly in size: some may house as little as 5U of rack equipment, while others can have over 40U of rack space. Capacity also varies, with some models having a load capacity in the double digits, while others can hold as much as 350 lbs. Most protrude from the wall around 20 inches or so, although some examples have a depth of 30 inches or more.
Low Profile Racks
If wall mount enclosures are already a space-saving measure, low profile options take that goal even further. As such, they are a more efficient use of space, but they also place stronger limits on how much can fit inside them. Their depth is often around 15 inches or less, and their rack space capacity is usually in the single digits, though some examples can have as much as 16U. Sometimes, due to the low profile nature of the enclosure, components will mount vertically instead of the traditional horizontal rackmount set up. Others feature a hinge with a “tilt-out” rack that can only accept smaller media components and patch panels.
