Top Shelf TSB-2438 Universal Heavy Duty Window Air Conditioner AC Support Bracket -Holds Up to 200 lbs., No Drilling or Tools Required, White

This AC support was easy to assemble and install. No drilling required was the best part. This support made installing a 160lb window AC much much easier. Make you measure your AC prior to purchasing this AC support. Take note of the recommended usage. Reach out if you have questions. You may be able to still use it if you have a 2 piece AC.

I looked up a how to video on YouTube before purchasing, (which is not really very good at all considering it looks like it was uploaded by the manufacturer). I thought this was going to be so simple, just assemble and place in window, done! But no. My window has an inner metal frame and neither method of placing the shelf inside the windows frame or outside of it would work. It just left all kinds of gaps and empty spaces around the shelf, and around the accordian extenders on the air conditioner. Too bad, its sturdy construction and you just cant possibly put an AC in a window without some type of support, but every windows construction can be unique, and this shelf is not a one size fits all. I just recommend you study your window frame carefully before buying.

Ive owned this bracket for over a year now with two installs and one removal and even with the window being in an odd spot due to furniture in the way, Ive been able to install it by myself. After the first setup and test to make sure its sturdy, I was able to pull it out and place it directly back into the window without any changes to the bracket. Definitely glad I didnt cheap out and got a high quality Air Conditioner Bracket which didnt require me to drill into anything especially since my window frame is metal and not wood.

This shelf has been fantastic. I was not sure if I wanted to buy it due to the price, but it was worth every penny. It was easy to install and did a great job. I got a huge window AC to cool down my living room, dining room, and kitchen so the AC unit was about 90lbs and I didnt want to ruin my windows by not using a brace. This shelf was easy to put together and fit into the window and gave my AC unit the extra support it needed.

This was the easiest AC bracket I have ever installed (took me like maybe a minute or two), and my AC is definitely not going anywhere. Im totally inept when it comes to assembling anything, even with detailed instructions, so this bracket was such a pleasant surprise. Well worth the money.

I had a nightmare time trying to install my 12000BTU AC in my condos window. The window is old and the sill is strange, and other brackets that required bolts just didnt line up properly. I decided to go with this one after reading the wirecutter review and wow did it do the trick. I simply installed the arms and the locking mechanisms and it fit just right. It turned a project I dreaded doing into something I found quite easy and fun. Would buy again.

With other reviews on this item I was hopeful this product would do as advertised. It is functional as a support for my large window Air conditioner. If you want something that will hold up large 80+ lb ac unit you will get it here. The reason I did not give it a 5 star is because it did not come with clear instructions and there are no videos online that address this specific install. Putting it together is a no brainer i had it together in around a minute. The install on the other hand took me around a half hour to get the support system in place accurately. Making sure to have the tilt if any to the outside not to the inside of the window was a bit difficult. I live on 3rd story of the building so it is difficult to dangle out the window and adjust. It did finally get to the spot I needed; however it left many large gaps to be filled. We have windows that are tilt in to clean and deep casement. If this is the type you have, make sure you get rigid foam boards to fill gaps because there will be many. Once filled and in place it works wonderful. No longer do I have to worry about the unit falling out of the window.

I now have four of these brackets. They are very useful for installing any window air conditioner. Even the smallest A/C units weigh 30-40 lbs and that is a lot of weight to be moving around in awkward ways. I first bought one for my daughter after she dropped her A/C out her back window. It is important to visit the Top Shelf website to see if the unit is compatible with your window and wall thickness before purchasing. You dont need to use any fasteners with it but there are two holes that can be used to screw it to the window frame and I have used a couple of screws to attach mine. Although the price seemed a bit high to me at first, after seeing how inferior some lower cost units were in comparison, I think they are a good value.

I purchased the Top Shelf TBS-2438 air conditioner support to hold a very large unit. Assembly and insulation were easy. It took a few minutes to adjust the position of the supports against the exterior wall, to accommodate the wall thickness. However, you should only need to do this once, unless you plan on disassembling it each time you use it. Since I have vinyl windows I was concerned with damage that could be caused by resting the air conditioner on the window frame and holding it in place with the upper sash. The thickness of the metal and painted finish are better than I expected. And if and it is very sturdy, if you assemble it correctly and make sure it is level. I am pleased with the product and can recommend it.

I have an older house with a mix of windows - some with storm window frames, and newer ones without those frames. This bracket will not work on the windows with storm frames because it is designed with the assumption that the sill and stool will be continuous, but in the case of the storm frame, the bracket cant sit properly on the stool -- the horizontal piece in the front -- because the frame gets in the way. Also, the spring-loaded buttons that are supposed to lock the support arms in place do not work in unison. That is, when one button is engaged in a hole, the other is compressed within the frame and off-center from its corresponding hole. The bracket is fairly sturdy, but I am very disappointed overall in its performance.
