Product review (3 stars): Won't work with DELTA 54613-RB
This hose will not work with Delta 54613-RB. The tapered end that attaches to the shower wand is too narrow, thus it will not stay in the holder, and constantly falls. It did thread onto the wand just fine, and may be great for other models and products, just not for the model number I owned.  Just putting this information out for others.
