Question: Do hooks come with brackets?
Document: 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.
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.
I ordered these wall mounts and really it is just thin metal for around $25 at the time of writing this. When they arrived they were missing the mounting hardware so I had to return them.I went to the hardware store and bought shelf brackets that cost $5 each, plus 4 lag bolts at $0.30 each and was actually able to get a stronger mount than what these offered, plus the shelf brackets come in larger sizes. I really would stay away from these.
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.
These brackets were exactly what I was looking for. They allowed me to install a 120 inch screen with ease and I was watching movies in under 30 minutes . They are sturdy, functional and very easy to install. As an added bonus, the brackets make it much more simple to take the screen down too. I primarily use the screen in my home theater room but during pleasant summer evenings I like to take the screen outside and watch movies in the back yard.
This product is great and does everything it's advertised. It was also easy to install, the only issue is the lack of directions if your not a DYI person but I was able to look at the picture to figure it out.
This is great for the purpose. As a novice carpenter I had too much torque on my drill setting which caused the threads of the screws to deteriorate. Otherwise I'm satisfied.
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.
There isnt much you can say here. Did exactly what it was supposed to. Supports the Elite Screens Screen beautifully.
No instructions on how to use these. I have been trying to find some youtube videos - but couldn't so far. Thanks to elite screens customer support - found a link to the manual at [...] - not exactly for the hardware that was sent with the bracket, but at least this showed me the basics. I am updating the rating from 1-3.
