Document: I am using the elite 125 inch electric screen and these work well.
There isnt much you can say here. Did exactly what it was supposed to. Supports the Elite Screens Screen beautifully.
Did the job for our projector screen. Honestly, I was doubtful after I saw their size and simplicity, but they hold up very well!
These are nice. They worked well with my 120&#34; Elite Screen that I ordered. I read that you need to order this as the elite projector just comes with a basic mount.
I imagine with a much larger screen it way not work as well.I think the product stinks, but I got it to work and it looks nice. Therefore it's acceptable.
It's kinda of odd how these work. I ended up bolting these to the wall and then suspending my screen from 4 screws and washers. It works. It looks nice. However, I wonder if it couldn't be done better. Having a screen that is 140 inches across and only mounted on the ends feels like it won't last the test of time.
I used the bracket to hang the Elite manual 120&#34; screen. I used toggled bolts to hang these bracket for extra stability and they hold the screen very well. I can foresee it will last very well despite of pulling the screen multiple times on a daily basis.
We needed our screen to be off the wall by about 1.25&#34; (due to a whiteboard behind it) and so this bracket was the perfect tool for the job. Exactly what we needed. You can even decide just how far forward or back you want the screen (really the hooks that will hold the screen, but in turn the screen itself).These are very utilitarian. They 100% work, but aren't the most sightly brackets.
The L-Brackets are made cheaply. One of them was not straight; it was twisted at the elbow. The hardware that is included is really cheap too. I had to use my own screws as the ones provided stripped immediately. One of the karabiners broke at the joint and doesn't close all the way unless you force it. All in all, I was able to mount my screen and it does look nice and professional.
The brackets made hanging the screen easier as it comes with all the hardware to mount to drywall. I am glad I had these as the screens do not come with any mounting hardware and would  be hard to mount unless you had studs in the perfect spots.These give you some flexibility on leveling your screen and give you 3 secure screws to the wall where the screen only has 1 hole if you were trying to mount it straight to the wall.
Answer: no
