MantelMount MM340

I bought the refurbished product, which pretty much looked new except for the pulling handles which was slightly damaged.The quality of build and sturdiness is apparent as soon as you open the box. Very impressed. It's solid, but that also means that it is a bit painful to install (and rightly so). You definitely need 2 people to mount this with the gas piston actuating mechanism attached to the wall bracket.DO NOT EVEN CONSIDER mounting this directly into the drywall with anchors...bad bad idea. The mount itself is crazy heavy, so the anchors will not hold them. As you can see from my pictures, the studs behind my fireplace wall were located such that I had to mount the wall bracket off-center, which is not a problem at all. You can then center the gas piston so that your TV remains centered.As someone else has mentioned: the installation instructions are pretty decent, but they do need some work, as some parts are a bit ambiguous. Improper grammar or emphasis can alter the meaning or the capabilities of this mount. It took me some figuring out to realize that it's perfectly fine to install the wall bracket off-center.Only other item I can think of pointing out for installation are the tools: you will need drill/drill-bits, a ratchet with a socket set is also super useful. I highly recommend having a drill with the right socket when mounting the wall mount onto the studs. That thing is heavy and you want to get the anchor bolt in as fast as possible and given it's length it will take you forever if you are using a ratchet. I used my power drill to get it about 75% in and then went with a ratchet the rest of the way to finish off and to prevent over tightening. You will need an socket extender to adjust the gas piston settings. Including some of the tools like the socket and the drill-bit would be a nice touch, but I am not going to hold it against the manufacturers. I have a small bubble level with a magnet that sticks to the mount during install which was absolutely invaluable when I was installing the wall bracket whilst trying to keep it as level as possible. I definitely recommend that Mantelmount consider including that with the purchase.The primary issue for me (and this is not a con of the product, but more my particular setup) is the forward motion of the mount when moving it down. This is a MANTEL mount....meaning it's travel orbit is designed to avoid hitting the mantel piece present in most fireplaces. My fireplace does NOT have a mantel piece, which makes things less complicated, but the forward motion also creates an issue specific to my living space. My living room isn't the biggest, as a result of which moving the TV down to eye-level also means that it is now closer to our couches/seating arrangements, which can be a problem when you have a large TV (we just got a 65")...this is the ONLY thing about this mount that is bothering me. I am not happy with the fact that the TV is so close to me when it's moved down to a comfortable position.What I really need is a mount that limits the forward motion and keeps the degrees of freedom down to vertical and swivel. I don't think such a product exists, but I wish Mantelmount would provide that option.....that would be a fantastic buy.All in all: I would buy from Mantelmount in a heartbeat....this product exudes quality.

Works great. Took two of us an hour or so to get it installed. It pulls out and down so can clear a small mantel. Swivels a bit right and left, no downward tilt. The handles aren't the easiest to grab, but it gets the job done.

So far so good. It looks and works great. But the installation was a bear. I'm not super handy but I'm no slouch either. It took me 6 hours to install!That's because(1) a screw stripped. I didn't discover this until I had to take it out (because I installed a part upside down). Had to use an oscillating tool to cut out the stripped screw!(2) Hard to get the TV to hang exactly level. I needed to mess with installing the rack 1/8 inch higher on one side than other. Lots of trying, taking it off the wall, etc.(3) The mount didn't really fit the TCL 55 inch that I bought. Basically the TCL holes are too far down on the TV for the mount to work well. That means you need to improvise in a bunch of little ways.One tip I'll offer is that if you want the TV to lean forward (instead of backward, which was its natural position and which is just wrong for a TV above a fireplace), I needed to use spacers that didn't come with the mount. (Not enough spacers were included). I used six additional washers where the mount attaches to the top holes of the TV; but I used no additional washers where the mount attaches to the bottom holes of the TV. Basically that pushes the top of the TV further away from the wall, tiling down instead of up. I'll attach a picture of the washers.All in all, a looooong day. (Maybe I'm not so handy after all!). But looks good and works well.

Great product if you're constrained with a higher than desirable bright for your TV. The system provides the ability to lower the TV and create a more comfortable view.Great range of motion, the fit and finish is impeccable, I used it on my 55" TV with no issues. I also added a soundbar bracket below the TV, it fits without problems. I really like the cable management system, the system comes with zip ties and anchor clips.Self levelling: plenty of options for you to correct the level of the TV.Interference with possible outlet: in my case the top of the carrier arm was exactly where a recessed outlet box was -- no issues there there is a half inch gap between the wall and the arm itself.The only downside or important items to consider before purchasing I can see are:* Weight: the system weighs more than the TV (I want to say 35 lbs)* Install takes 3 hours end to end* Make sure to measure twice and drill once, your going to need to have 4 anchor bolts drilled in the studs.Overall super happy with this! Well worth the effort. I put some pictures up for folks to see what it looks like and how low the TV can go, it's quite impressive. Happy building!

​I originally installed this pull-down mount in my game room back in 2020, and it has been the MVP of my setup ever since.The pull-down function is clutch and a total game-changer when street racing in GTA or caught in a shootout in COD. Being able to drop the screen to eye level for that extra focus makes a massive difference. Six years of constant use and I have nothing but praise for it.​The build quality is top-tier and the materials haven't fatigued one bit. The motion is still as smooth as day one and I love how it kinda sounds like a DeLorean when you pull it up.I’m currently prepping my garage for a new TV and would honestly love to get another budget permitting.10/10 would recommend for anyone looking for a great tv mount.​P.S. My wife loves this thing too, she finds it very... uplifting.

This was not my first MantleMount, however; this was by and large the most capable. Our livingroom/great room combo lets me watch TV while cooking, which is great, but not so much if you're sitting in front of it. This pulls down to make it more comfortable. I liked it so much, I purchased another for my boy's room where he has a bunk bed. he can pull it down to have his monitor either up for him to game or down for him to use as a monitor. They are great, albeit costly. They are worth the extra money and I would not hesitate to buy again.

I purchased the MM340 mount for my Sony 65", 54.4 lbs X90L to mount over the fireplace. The installation is a bit cumbersome with numerous things to consider and not all Mantel Mounts fault. For one thing one of my 2x4 studs (right of centerline) was not space 16" apart but 16-3/4". A second and third issues- the 2x4 stud is at the CL (centerline) of my fireplace mantel. And the 120VAC receptacle and the TV cable conduit is mounted left and right of this center line 2x4 stud about 17" above the mantel. Therefore the 4" wide lifting arm would have block the AC plug or RG-6-HDMI cables. So the centerline of the TV ended up about 3" left of mantel centerline. I wish the wall plates was longer than 28 inches , 33 inches would have been ideal to screw in the four lag bolts on the two 2x4 studs left and right of the center line 2x4 studs. Also when mounting the brace extender per instruction, I could not get the extender handles to 1" below the TV bottom but it sits at 2" below the TV bottom. So I figure the minimum bottom wall frame should be 4" above the motel. I wanted to TV as low as possible. So I mounted the lifting arm about 3 inches left of centerline to prevent the lifting arm from interfering with the cable conduit and the 120VAC receptacle. The remainder of the install was easy. I triple check the exact 2-1/2" lag screw location (because of the overall weight -probably the most critical part of the install) The tension bolt did not need any adjustment (zero). I went up and down easy and held the TV at any position. I'm very please. I love how it smoothly lower or raise to any position. Good general detail instructions (hard to cover all scenarios). Hardware and material is heavy duty and mostly functional. So overall the MM340 is a Five Star, highly recommended. I did call the help line but the tech rep just repeated the written instructions and didn't concern himself with my specific needs.

UPDATE (03/2026)After so many years since I had a replacement arm sent because of QC issues, I had to contact customer service again. The piston popped out of place. I contacted them in the hopes they could help. Despite being so many years later, they're still going to sent a replacement.I then asked if there's something I could do to prevent this from happening (7 years later, btw). Well, apparently, I've been keeping the TV in the down position as a default. They recommended that you bring the TV up to store every night. Despite this possibly being my fault, they are still replacing the arm.Bottom line, even though I was not using the mantelmount as it was intended, it still lasted for a long time. And even though the company could have told me 'it's too old and we have no warranty obligation', they instead ASKED CURIOUS QUESTIONS (not to get out of helping, but just checking to see if they need to fix something), gave me advice on what to do from now on, and are shipping a replacement arm. I hope to get it in a few days. I very much appreciate Mantelmount, and now I feel a sense of brand loyalty. When I buy a new TV (maybe in the next couple of years), I'll likely upgrade the mount because of 1. brand loyalty and 2. I'm confident I'll be taken care of down the line.-- END UPDATE. Original review below this line ------The MM340 is a solid piece of engineering. Though it seems quite intimidating to install, if you follow the directions precisely and take your time, it's really not that hard. You do need to be comfortable with power tools, so if the most complicated DIY is Ikea furniture, then I would hire a professional, or I would really read up on every aspect of this installation.Even though I was pretty careful, I still ran into a problem. One of the gas cylinders in the arm twisted in such a way that the ball in joint between the adjustment screw and the gas cylinders broke. It was pretty scary. After assessing this, I called them up.They were extremely nice. During that call, they requested a photo of the issue so they could figure out what to do. I did so. Only a day or so later, they contacted me and said that it looks like it was a defective arm, so they sent one out to me for free! I had undo the mount from the wall so I could swap out the arm. After that, I got it up and going within a couple hours and am very happy with the result.So, the build is good, the QC probably needs some work, the install was "easy" and the whole thing seems quite durable. I definitely recommend the product because it's a quality piece of engineering plus the customer service was really top notch.

Easy to use. Good product. Seems durable. Enjoy having (almost) proper viewing height and soundstage (where voices are not placed below screen).If your mantel sticks out it's kind of a pain to get installed to the lowest possible drop. Measuring many multiple times did not get to where I wanted. After second failed install attempt I found it was easier to install the safety bolt that retains the dropped position and man handle it to find the best height that way. Faster and better placement that I wish I'd done in the beginning saving a lot of time. Stupid me reading instructions. It's heavy though so normal sized people might need a helper with this.The fact it can't angle the screen is a pain if you have a reflective screen (like OLED) because it reflects your room causing viewing issues. Solution? Use long bolts in top VESA mount with thick washers to permanently angle screen down.Bit scary snap up with OLED as I worry that since it's all glass it might crack. (Yes it's adjusted to minimum gas shock strength). You need to hold mount when raising to avoid issues. Young kids can't be trusted with fragile tv's. Should have a soft bumper or additional gas shock to resist sudden shock when raising, but no manufacturer seems to offer this.The rails on the rear are visible behind the mount and look ugly with the multiple bolt holes looking like industrial racking. Should have snap on plastic to cover rear workings like my previous mounts, that were less visible due to not being drop down. Strange they didn't think of this. Or maybe you like the industrial look?Avoid using supplied bolts. They're thick and require predrilling giant holes. Get something like GRK RSS (Rugged Structural Screws). Smaller holes in your studs due to greater strength, they drill their own hole when installing and have a washer sized head. Plus, since you can see them in the mount, they are less obvious and look better.I still recommend this product! Just see room for improvement to make perfect.

Best decision

This TV mount did the job exactly as advertised!The measurements provided were bang on during the instal process.You can’t see the mount when it’s in the down position.It has been up for about a year and still working great, we move it a couple times a week for watching movies. Or to get the swivel function to see it better from the kitchen.

Sturdy and works great. Set up took a while to figure out. Removing one star as we can see the wall mount under the tv when its positioned up/ away.

This thing is great!Not sure if the instructions changed compared to some previous comments but i found them very detailed and had to read a couple of times to understand what & how. But it all made sense.Make sure to measure and mark everything properly, your center of the mantle and studs.It is better to have 2 people install it, but doable being alone, which took about 90min. Hardest part doing it alone was pulling the arm down to install the security bolt.Otherwise it holds the TV well, easy to maneuvre and adjust.It is pricy but very happy with the item!
