Tension Shower Curtain Rod Support

Well no matter how much I tensioned these things they eventually fall off.
This is usually the case because the shower curtain is left to one side or another making that side heavier. Or if you use heavier curtain rings type thing.
This is here to take up the weight a little. So after you tension the crap out of the rod use some of that picture frame 3M stickers and stick one of these at each end flush with the rod.
