Lanview LVR261706 rack accessory Mounting kit

You use cage nuts when you need to mount a product in your rack that requires a threaded hole. A cage nut is a square nut that has threaded holes wrapped in a piece of spring steel designed like a cage. This spring steel has two flanges that when pressed together allow the cage nut to be inserted into the square hole and simply clip in. When this is done, you now have a square hole that is threaded.
