It's like the carousel shelf in your kitchen that allows you the fastest access to your Fruit Loops. We took that Lazy-Susan design concept and utilized it in our Swing-Away Relay Rack. Now installing and exchanging components is hassle-free. The Belkin 19" Wall Mount Swing-Away Relay Rack (36"H/18"D) swings open to give you easy access to your components. Easy installation and ideal for space limited environments.
