Question: What is the actual height from suction surface?
Document: After installing a larger, bulkier Grab Bar in my own bath, my Wife and I decided she needed something less intrusive in hers. These are superb. They install easily. Are a great size for any hand. Hidden rubber strip grabs you back. Rated Very High Strength. Ordered two for Free Shipping. Then ordered Two more. INSTALLATION TIPS:  A popular Fiber-Glass Bath Liner is certainly strong enough to hold these with simple Toggle Bolts. If you use "Hollow Wall Expansion Bolts", be sure they match the actual thickness of the first wall surface.
I use grab bars in the bathroom. This little job is at shoulder height next to the tub and allows me to embark and disembark with ease and safety.
We bought this again after I had one for my dad to assist in his showering. My bathtub had smooth walls. We again bought this for my father-in-law. However, his tub surround that we used it in had bumpy walls. While it appeared to stick well, when a good amount of pressure was applied, it came off. I would only use this is you have a very smooth surface to place it on. Test it over and over again to make sure it is holding, before you allow someone to use this.
The grip part is almost 1&#34; in diameter with a black rubberized insert on the inside part of the grip contoured to fit your fingers; the grip extends outward about 2.5&#34;. The hand grip surface is white plastic, but it feels heavy enough that there might be a steel frame inside. The picture on the web does not do it justice, because they are trying to show you in one photo a complete view of the hand grip, including the underside contoured black insert.
If you have a tight space and you need a small grab bar, this is for you. You will have to locate a stub to secure it to, but then, you can rest confident that it will support you when you need it. No suction cups which periodically fail and can do so at the worse times. Plus, this grab bar is attractive and it's off-white color goes with any decor.
When I shopped I was looking for suction cup hand grips so I would not need to drill into my soapstone shower walls to mount the hand grip. It could have been better described! This one appears to be suction cup attached, but, alas, was not. Returned it and found suction cup ones at Walmart  :(
This compact, easy to install, easy to clean safety grip should have a place in every tub or shower stall regardless of existing accessibility needs. Not all such handles are rubber backed and it is a nice feature. It is important to hit the studs so keep that in mind. We used molly bolts to anchor the handle and it seems sturdy enough to support most adults and is far superior to the suction variety.
Easy to flip the lever, remove, and place it elsewhere.This screwed in model would be good in stairways. Suction types often don't stick to painted surfaces. Also, screw holes in drywall are easy to patch.An elderly neighbor fell down at the top of her stairs last year, had nothing to grab on to, and broke her neck and back, 6 vertebrae in all. She's alive, but her life is ruined.
When my wife first saw the picture of this hand grip (Moen LR2250DW), she thought it was one of those suction-cup hand grips and thought it was too clunky. But I told her it says that it's only 2&#34; wide, and the suction-cup ones were at least 3&#34; wide. So we decided to try it. When it came, we verified that it is indeed not a suction-cup grip and only 2&#34; wide and 9&#34; long.
I have an elderly parent that I'm taking care of and I was excited that Moen had come out with a product to assist my mother in and out of the tub and shower. Hastily I bought the product thinking that it was going to be a suction type of handle because that's what we're used to . Not the fault of Moen by any means but I didn't catch that part. When it arrived the tabs that conceal the screws were snuggly in and we had a hard time pulling them out (my mother insists on helping).
