Need extra height in your cabinets? These ShelfGene Glide-Outs are double height. Notice how the top Glide-Out is only a few inches tall. You can accomplish this because the shelf slides to you - which means you don't have to force your hand in there! Hi! I'm Elizabeth Beach Hacking of ShelfGenie MA (S. Shore, N.
