Needed to clear out closet space for my home-for-Christmas son.  His closet door wouldn't close all the way on one side with the shoe organizer hung over the door so my husband screwed in a board to the studs inside the closet and it's working out well.  I think out closet door was a pretty tight fit at the top and the hangers are a little thick (need to be to hold the weight).  I think for most closets it will be fine but check that prior to purchase I'd say.
