Question: How do you get it onto a grab bar that is already installed. Does it come apart?
Document: I needed to get a shower setup for a relative that was versatile and safe. I stuck 2 grab bars in the shower (one horizontal under the controls and one vertical just off to the side). This slides up and down the vertical bar and stays in place perfectly. It holds onto the shower sprayer nicely.
Purchased this for attaching to grab bar for upcoming hip replacement. Son installed grab bar vertically in shower, as I wanted it, and this works perfectly to hold the hand held shower head down low where I can easily get if while sitting on the shower chair. Comes with a larger and smaller semi-circular part to fit needed size of grab bar.
This was easy to assemble and use. I attached it to a grab bar in my shower. It didn't come with directions though.
This handy adaptor allows a hand held shower to be installed at grab bar level (within arm's reach), thus (1) providing warmth of shower spray on individual while sitting in a shower seat and (2) allowing the person using shower seat to bath independently.
This item is great! I ordered it for my mother that is disabled and installed it on her grip bar in her shower. Installed on the shower grip bar very easily about 3 minutes and seems to be made study enough that it can handle years of use. She also like the feature of the big handle to grab to move it up or down on the bar easily and turn it side to side. I recommend this for anyone that has a loved one with disabilities to help them in the shower.
Needed a replacement for the hand shower holder at the in-laws' house. Couldn't find the exact match for the one that broke but this looked like it would work. Turns out it's better than the original. Always good to get brownie points with the inlaws!
This bracket is very well made and extremely easy to install. The adjustment feature is an added bonus. I installed it for my father in law and he can now sit in his shower and direct the shower spray to his liking.
Our contractor told us he used this attached to a Grab Bar, and it works very well. Suggested we try it and so glad we did. Not only does it look good, it will work for safety also.
This does a good job of attaching your shower head to a grab bar. It has adjustments for various sized bars too. It's simple and works well. However, I don't know if it would work with a non-delta shower head.
The shower head holder for a grab bar  fit perfectly on the grab bar and stayed in place yet was easy to move if necessary. The hose for the shower head fit nicely in the holder and did not fall out. This was exactly what I was looking for.
Answer: yes
