When you’re looking to get small items off the floor, table tops or just out of the way, a wall mounted hanging corner shelf can provide you with a raised platform that can accommodate such things as plants, nick-knacks, framed photos and trophies. Also great for the rear speaker set-up of your home entertainment system. Make sure you know how to install these before you buy, and that you have the proper hardware as well.
