On the end of the rod there is a round white piece that is supposed to adhere to the shower making it stay in place, however, this piece had come off and slipped to bottom of the box. Needless to say it would not stick and I had to return it. I have just had a new shower installed in my Master Bath the old one had the glass door. Therefore, I was in a hurry to get this put up and didn't want to wait on a replacement to be shipped. I must say that these things happen and the only reason I did not send it back for a replacement is the time involved. The Rod was really nice and I loved the design.
