When you have a lot of guitars, you want to display them instead of locking them up in a case in a spare room. But you only have so much floor space for stands. So you have to move some to the walls on hangers. It can be a little nerve wracking at first but if you want to be absolutely sure your guitars are safe, a Hercules hanger is the way to go. They have auto locking features and hold around 15 pounds, and most guitars are under that weight ratio.
