My townhouse was built in 1981 and apparently then you did not have to put studs in the walls in your closet because I could find maybe three and they were nowhere near where I needed them to be to hang a closet system. Being able to put this up with one secured bar on the back of my wall was honestly the best thing ever. A few wall languors and this bar goes up and now I have a wonderful custom closet system!!! I’ve purchased additional pieces to go with it and I will never go back to anything else￼￼￼￼
