These are meant for wall mounting but since I don't mount anything to my walls I had to get a little bit creative. I received two with my twin stack add-on (which was an awesome way to package all of the hardware), so I used them to build a horizontal barbell storage rack using an extra crossmember to connect them. Since they don't have feet like an upright, I used some scrap wood to attach them to the windowsill behind with brackets (keeps them from tipping).
Basically these allow you to come up with your own solutions for storage and attachments depending on your space. And because they have the rack compatible 1 inch holes and keyholes, plus smaller holes for mounting to studs, you have a lot of options for DIY type stuff.
