Adastra 3U Support Module, Black Steel 19" Rack Shelf

This Adastra support module gives you a solid shelf for your 19" rack, taking up 3U of vertical space. It bolts into standard rack rails and holds gear that isn't designed to mount directly, such as small mixers, media players or amplifiers that need a flat base to sit on.

The module is made from steel with a black finish, so it sits in with the rest of your rack hardware without drawing attention. Steel keeps things rigid under load, which matters when you're stacking equipment that carries some weight. The plain black coating is easy to keep clean and stands up to the knocks that come with regular use.

At 3U tall, it fits neatly into a standard 19" rack (sometimes called a 19-inch equipment rack), whether that's a wall-mounted cabinet, a flightcase or a floor-standing frame. Rack sizes are measured in rack units, with each U equal to 44.45mm, so a 3U module gives you roughly 133mm of height for the gear you're placing on top. It's a simple, practical way to make use of space that would otherwise sit empty.
