    What is the reach of this mount?
    Aaron H on Feb 11, 2017
    BEST ANSWER: Thank you for reaching out to us, the arms are 20" each. The distance from the corner to the display will vary depending on the positioning of the studs in the wall relative to the corner.
    Is there a copy of the install manual available ?
    A shopper on Feb 14, 2017
    BEST ANSWER: Thank you for reaching out to us. The manual is in the process of being uploaded to the product page, in the mean time you can reach out to tech @monoprice.com and one of our associates should be able to share a copy of the manual with you.
    I can't find any mention of tilt adjustment despite the listing as "full motion" . Since we need something to mount fairly high I'm looking for a strong corner mount with some tilt to it. Does this tilt?
    David S on Feb 20, 2017
    BEST ANSWER: Thank you for your question. Yes, the mount will be capable of tilting. It will be able to tilt up 5 degrees and down 15 degrees. The user manual listed on the page will indicate this in diagram 4.
    Will this mount work on inverted corners, i.e. corners that jut out into the room?
    Raymond D on Feb 14, 2017
    BEST ANSWER: Hi Raymond, thank you for reaching out to us. I would not recommend installing this mount on an inverted corner. The mount was designed to support the weight when installed on a standard corner.
    "Designed for televisions from 37" ~ 63" or higher"

    So what's the biggest screen size it will accommodate?
    A shopper on Feb 20, 2017
    BEST ANSWER: Hi Shopper, thank you for reaching out to us. The deciding factor on the size of the display comes down to the shape of the corner and the overall width of the display being mounted. Based on our guidelines, we were able to conclude that the mount would fix most 63" displays when installed into a 90º corner. Some 70" displays for example may have a larger screen size but smaller overall width and would work with this mount. Beyond the 63" size it would be the customers responsibility to measure and verify that it will work for their specific corner and display. Thank you.
    If the two wall plates are installed on the same wall what is the mount's depth (thickness) when fully folded up against the wall?
    A shopper on Feb 14, 2017
    BEST ANSWER: Thanks for asking, It would be about 3 and 3/4in, there are other wall mounts that would perform better in that orientation, but it is an option if necessary.
    I want to mount a small tv 25" or 32" in a corner of small bedroom. Will this mount handle this small of a tv ??
    A shopper on Mar 31, 2017
    BEST ANSWER: To determine compatibility with a TV mount to your TV, please determine the VESA mounting pattern on the back of your TV. It is the 4 screw hole square formation on the back and it is usually listed on the TV specs or you can find out by measuring it yourself(measured in millimeters). You would want to be sure that the VESA of the TV is between 100x100 to 800x400 and also that the weight of the TV is not heavier than 132lbs. However, the mount is fairly large so it would likely be able to be seen sticking out from the back of the TV. I hope this helps, thank you!
    can the mount be installed upside down so the arms connect to the outside of the mounting plate eg left mounting plate arm would connect to the left side of the mounting plate?
    Tracy T on Jun 28, 2017
    BEST ANSWER: YeS you can. You can do this with practically every articulating mount. The question would be, why would you need to? After all, all of the mounts are symmetrical.
    Will this mount work with a UN65KS8000FXZA mounted in a 90 degree corner? TV needs to be 45 degrees to the corner.
    New User U on Apr 3, 2017
    BEST ANSWER: I can't speak to a specific model of TV, but it definitely works in 90 deg corners and can put the TV at 45 degrees. Seems sturdy enough for a bigger screen than the 42" I used it with.
    What is the total weight including packaging of this product?
    A shopper on Jun 18, 2017
    BEST ANSWER: Thank you for your question. The total shipping weight of this mount will be 22.50 lbs.
    How much does the bracket with packaging weigh?
    A shopper on Jun 16, 2017
    BEST ANSWER: Thank you for your question. This mount with packaging will weigh 22.50 lbs.
    will this mount work with a TV that has a 500mm x 300mm vesa?
    Kurtis D on May 17, 2017
    BEST ANSWER: Thank you for your question. Yes, this mount would work just fine with a TV that has a 500x300mm VESA. Just be sure that the TVs weight does not exceed 132 lbs, which is the maximum weight the mount can support.

    Can this be mounted between two parallel walls, roughly 42" apart?
    Paul F on Mar 5, 2017
    BEST ANSWER: Possibly? If the walls are parallel, is the TV going to be parallel or perpendicular to the walls? If parallel, I would recommend a standard wall mount. If perpendicular, I would try running a 2x6 side to side and again using a standard mount (depending on size/weight of TV). Look carefully at the range of motion on this mount. Good Luck!

    Nice and Solid Mount
    This is a great mount especially for the money, it was heavier and sturdier than I expected. The level is a nice touch, would be nice to have a template for mounting locations. Just remember to tighten down the bolts right behind where the tv mounts.

    Great, solid mount, but heavy
    I needed a sturdy mount that would hold up our 100 lb Samsung Plasma TV and also position it in the corner of our new family room. This mount works great for this purpose. I actually mounted both parts on the same wall, but I mounted it close enough to the corner that the TV sits in the corner at around a 20-30 degree angle away from the wall facing our sectional in the opposite corner of the room.
    The hardest part was trying to mark the holes, drill the pilot holes, then hold it up while I mounted it to wall.
    It was a bit too heavy for my 10 year old son to hold up, so I had to enlist my wife's help... which meant I did it on my own.
    Definitely sturdy enough for our large, heavy TV and the movement to get to the back of the device is smooth and silent if I need to change out cables or access the back.
    Highly recommended.

    We absolutely love this corner bracket! It fits perfectly in the corner where we installed it and it was extremely easy to install. It is very sturdy. I highly recommend this bracket!

    For the price, this wall bracket is built "like a tank" and handles my 65" Flat panel perfectly. Its design allows a level of mounting flexibility not found with other much more expensive brackets. It would have been helpful to have been provided exact measurements on the website, but i was able to create a mounting template once the unit was delivered.

    Corner Mount
    This corner mount is just great! My electrician said that it was very easy to install. He liked it so much that he may order some and offer them to his clients. The swivel makes it very easy to adjust for easiest viewing. I highly recommend this Corner Swivel Mount to others.
