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 didnt want to pay ninety-nine dollars for this -- but there was no other solution. I must say, when it arrived I was very impressed with the packaging and build quality and my angst over the price dissipated to the point where I could swallow the price. Packaging -- it comes in foam packaging with cutouts for each part so they safely stay separated and undamaged. Build quality -- theres no way this is bending and it looks to be powder coated for a great finish that wont peel or rust easily. Problem: I had to return it though because it wasnt obvious to me that it would add an inch (eyeball measurement) to the overall height of the window sill. This made it impossible for me to fit my AC in the window. Even if I had been able to fit it in, I wasnt sure I liked how the feet were pressed against the bottom edge of my vinyl siding shingle (is that what its called?). I wish there was a way to lower the legs somehow so that I could place them squarely on the top part that is closest to my actual house where it wont be subject to the same pressure. I worried that over time the vinyl siding would crack.

Its important to note that if you have wood windows without an inner frame / lip on the side of the windows, this *will not work*. The tabs on the sides need something to pull back against, if you rest the bottom of the bracket to push inward against the outer edge of the sill, then the A/C will be tilted forward and drain into the room. That said, this is mostly a documentation problem. If you have a window for which it will work, the product is very well made. It does seem like a few modifications could have made it usable for wood windows (e.g. second set of arms with a screw rather than tab-only option.)

Fits our very difficult-to-fit for other supports Brownstone window. Took all of 5 minutes to get it set up and installed, and it supports the AC perfectly.

AMAZING bracket. I have never owned one before now, but I cannot imagine there being a better product. No tools, assembles in under two minutes, lightweight but STRONG. It sits in the window, you adjust it to fit better and voila, the perfect platform for your A/C unit. The A/C unit slides onto it like a knife through warm butter. Is it expensive? Yes. Is it worth it? Every penny. Spend the money on quality and innovation.

This shelf does hold an air conditioner; mine held a large unit. It wasnt incredibly difficult to assemble. That being said, it did leave a gap at the bottom where outside air could easily infiltrate. I also found damage on my sill. Additionally, The water ran out of my unit down the closest leg and painted my brick wall white. It also rusted away all of the paint on one foot and introduced rust on the other foot. I also had difficulty keeping the pads in while installing the mount. Its a good concept but the product needs a little more quality control.

Product is very solid and fits really well into my window frame. Did slightly adjust where the AC lines up with my window so the lip doesn’t exactly align, and some air gaps increased, but that’s because I have an old style house where the side panels don’t line up with where the window slide open. Some rolled up towels were able to seal the gaps. Definitely feel much better about having my window AC above the front of the house, especially if we experience any big earthquakes, I feel like this will actually stay in the window now. Anyways, my product had a slight defect (defects happens even with the best product manufacture design), I reached out to customer service, and they sent me a replacement piece right away. Replacement piece works great. Would buy again.

Yes, it doesnt fit windows without a ledge on the outside of the window. But it looked a bit sturdier than others on the market, and the seller does state that it wont work with windows without an outside sill, so not theyre fault. I was able to make it work by getting a wide lead bar and a 1X3 board from the hardware store and using it as a brace on the inside of the window buy inserting them both into the hollow space in the front wings that go on the inside of the window. Both extend out a few inches and brace it against the inside molding of the window on each side. The metal bar was because I have a heavier AC, and the board would have bowed. Not the best solution, but it did look sturdier than the others on the market so Im not sending it back. Some of the other brands only had 1 stabilizing foot in the middle, I like that this has 2. And I like the fact that I dont have to drill holes in my window sill. So Ill nix one star because I wish it fit windows without an outside ledge. Oh, and the holes arent supposed to line up on the leg depth adjustment. Its a little confusing, but it was designed that way to allow you to make more subtle depth adjustments and still keep the metal sturdy by having fewer holes drilled into the metal. Kind of confusing, but I understood why once I started trying to adjust them. Im happy I dont have to drill holes into my window sill.

Impressed by sturdiness and ease of use. More expensive than many alternatives, but worth it for the strength and ease of application.
