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

I thought we were going to have to hire someone to secure our window air conditioner in the attic, but this works GREAT!! It was easy to assemble, and easy to install in the window. The air conditioner is now securely in place. When I was searching some commenters thought it was too expensive, but I would rather pay a little more to have something I know is secure. We just had new siding and windows installed last year, so we also like that this doesnt need to be attached to the outside wall to be secure -- so there are no holes in our new exterior!! Love it!!

I have to install 10 of these in an old brick apartment building in Brooklyn with thick walls. I tried a couple different types of brackets from Home Depot but they wouldn’t work. Even though the walls are thicker than recommended for the product all I had to do was drill into the wooden window frame so the sliders have some where to support. Very easy to setup and install. I bought 2 white and 3 black initially and I will buy another 5 to finish the building.

This is probably the most attractive window A/C mount, but the position of the bottom rail forced the unit to sit under the window instead of in front of it. This meant that the A/C units top rail didnt have anything to grab onto without additional parts. To keep the A/C unit stable, I had to cut down a piece of wood to wedge into the window track so there would be something for the A/Cs top rail to grab. After painting the wood to match the window, it all looks perfectly fine... but I wasnt expecting the extra work. Ideally, a universal mount would provide all of the hardware necessary to make install relatively makeshift-free in a large number of windows. I slightly prefer the Jeacent mount thats sold for roughly the same cost, although that mount also required me to use a wood shim to get the A/Cs extension panels to sit flush around the window frame.

UPDATE: Third year of use. Still absolutely love this product. It is super easy, super adjustable. Im about to buy another cause new A/C came with an included shelf/bracket like this custom made for the unit. It is junk and Im throwing it out. I slid this one back in place and all is good. Remember to buy yours in the fall when the prices are low. It is spring and the price is jacked up over $100. I take it down and store it each year. Another tip, mark the hole you used when you bring it in for the year cause you will likely store it compressed and hate to have to go through hanging out the window and readjusting to find the right hole. One more, some of these reviews complaining the adjustment pins dont line up with both sides. Ignore this. They are designed that way to allows more precision and less slippage. It will cost you a little on install and storage time but makes it fit oh so perfectly in most any window. ORIGINAL REVIEW: Engineer here. I really like the design of this product. I never thought this could be this easy. No tools needed, adjust to fit window with size adjustment holes and place it in the window. Placed A/C in place, super sturdy. Never had my A/C this well supported ever. Added one piece of insulation, far less then I usually add each year with adhoc supports. For all the different windows out there, this thing is really well designed to fit most. I dont expect it to be perfect as the task here is tough. BUY.

Youll likely need a ton of insulating foam to seal up all the cracks this leaves, but it solves a niche issue and for that I am very thankful. The rubber feet pads are terrifyingly hard to press in and fall out almost immediately - also the spring loaded button stops for the arms are not particularly made the best - one refused to pop out no matter what I tried. Rest of the item seems very sturdily built. Like some other reviewers I have outside flush vinyl windows and no real good way to brace a heavier AC. The last AC I put in damaged the window due to its weight so I needed something to help with the bracing, but didnt want to fabricate my own wooden bracket or shove a 2x4 in my lawn. I set this flush with my inside frame, so the arms in front grab on the sides of the window sill - then used a ton of foam to seal up all the cracks. Not the prettiest but definitely is getting the job done so far.

I tried supports from Home Depot and Lowes but none of them worked with Vinyl windows, they required that you either screw into the window frame or the mount was too far on the inside of the window to allow the side panels to work. This product is very sturdy. No tools required and fit almost perfectly. Leaving a nice sturdy channel to rest the bottom of the air conditioner into. I took one star off sturdiness only because the bottom bracket does have a slight bow to it with the weight of the AC unit. Nothing I am overly concerned about though. Very pleased with the frame and would highly recommend to anyone with vinyl windows and a 10k btu or higher window unit. My windows are 36 wide and this worked great. Note: I had to install the bracket further in with the tabs on the window casing not on the window frame as instructed. There is only about 1/4 inch or so on each side that the metal tabs could rest on the window frame, which the adjustment holes on the sill bracket did not have fine enough adjustment for and I would not have felt comfortable with so little (1/4 inch on each side) holding the AC unit in. So using the foam strip on top of the AC unit and some Duck brand foam (https://www.amazon.com/gp/product/B002GKC2WQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) it works fine.

I had my old windows replaced with vinyl after air conditioner season last year. When I recently went to install my ACs, I discovered they no longer would mount the way they used to without the support of the old storm window housing along with not being able to drill into the new window sash or sill. I had no idea what I was going to do until I saw this product. It is absolutely perfect for my application. It took less than two minutes to put the pieces together and get ready to install. I was impressed with the sturdiness of the bracket and the way it locked down by moving the legs closer to the exterior of the house one click at a time. By the time I was ready to hoist the AC onto it, I had 100% confidence the bracket would stay firmly in place. As an added bonus, the thinner layers of packaging material make for excellent flexible insulation around the areas where gaps will ocur below and to the side of the unit. Also, because I have vinyl siding, I used some of the styrofoam to put between the feet and the house.

The bracket is sturdy metal. It goes together and installs easily and should work well. The problem with mine is the front support wing lock pin was broken upon arrival and sitting in the bottom of the box. Some of the paint is also chipped, which will cause faster rusting in Seattle weather. I can fix this, but should not have to for this price. I am waiting for a reply from their customer service and hope they will just send a replacement wing rather than having to hassle returning the whole thing. If they send a replacement, Ill be able to increase the sturdiness to 4 stars The leg lock pins do not go into both holes at the same time as some others noted. I thought they were broken, but the instructions note only one pin locks at a time. *Update 7/8/21: The Top Shelf Team was quick and responsive. They replied quickly and sent a new wing to replace the broken one. Kudos and thank you to them. Upgraded rating to 4 stars.

Super easy to set up. Read instructions, and it literally takes 5-10 minutes. It is very sturdy, and good quality. The reason I can’t give a good rating and my complaint is that for the price, why on earth would they leave the part where you put your AC with a glossy, very slippery surface?? Why not ad a gritty texture in the paint there, or ad a plastic slip proof surface, so when you are setting the AC on it, it isn’t susceptible to sliding around or even sliding off to possibly a long way down!? I was (an still am) shocked how slick and slippery it is and I want to shift my AC around and put more foam around our window to seal it better, and opening the window and moving it really does make me nervous, because of that huge design flaw.
