Question: work in shower
Document: I purchased this to work on a shower door. This lever-type suction is not as good as the plunger type because you have to mate the surface correctly the first time, whereas the plunger type lets you increase the vacuum -- which is handy if there is any leakage. However, this lever-type is cheaper and good enough for occasional use. It is also handy to pick up furniture or objects with smooth surface. It creates an instant handle.
I bought these to adjust a 3/8 thick shower door. I was amazed how well they worked, I'd recommend them highly !! !
I've never used the pro-type suction devices with the button pump etc, but for about ten bucks, this guy holds really well. I'd be afraid to trust my life to any of these devices including this one, but I couldn't budge it once attached. Tested on glass shower door, and granite counter tops.
The FastCap HOD (Handle on Demand) is identical to a grab bar sold by Drive Medical for less than 20% of the cost. I use it in a fiberglass shower stall for support. It holds extremely well on smooth fiberglass. Make sure you check it for adhesion every time before use. The only advantage of the Drive unit is that it is white.
We bought these handles for a bathroom renovation project where we were going to put in frameless glass shower doors and a big mirror. The doors were very heavy, but these handles exceeded all my expectations. I wasn't at all confident that they would be strong enough for the job, but almost as soon as we started using them we realised that they were more than up to the task and they made the renovation so much easier. I would highly recommend them to anybody needing a cheap handle for a small job.
I'm remodeling the master bathroom, including a custom made frameless shower stall. The tempered glass is 1/4" thick and the pieces are large as well as heavy.Concerned about breaking parts of the heavy and cumbersome glass panels in installation, I started looking for strong suction cup tools to help safely pick up and maneuver the panels.I got two of these devices, and their quality and capacity exceed my expectations. The price was also great compared to other products.
Bought this to lift window air conditioners. Didn't work.
I gave it 2 stars because one handle did work properly.
This tool did not work very well. Not at all like more expensive models I have used for glass and mirrors.
It did not work even to hold on to flat glass for more than 5 seconds. I would not recommend this
Answer: yes
