Buying a folding wall rack isn’t a whole lot different than buying a standard squat stand or power rack. You’re going to want to pay attention to ceiling height requirements, the steel used (dimensions and gauge), where it’s sourced, the size of the hardware used, the build quality (this has a lot to do with where it is sourced), and what kind of finish the unit has. It goes without saying that price will matter, but most are priced reasonably.
This is still close enough to the wall to be space-saving and allow a car in the garage, but if you need closer because your garage is just too narrow, it’ll have to be the Slim Gym. Folding wall racks are a great space-saving alternative to full-size power racks for athletes who want to train in their garage. Folding racks require only some empty wall space and a few inches of floor space to store, yet they open up into a full-size rack that’s almost as versatile as a normal power rack, and able to support more than enough weight.
