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

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.

I was really getting tired of damaging the sill on my vinyl windows with the weight of the window ac unit resting on it year after year. Not to mention the rigging of a temporary summer bracket outside every year. And where did I put the one from last year again??? So I went looking for something engineered for the job. Having an old farm house, this one caught my eye over and over as I researched. My initial question was is this really going to be worth paying 2 - 3 times the cost of support brackets at the big-box stores. That question was answered when the box arrived and I was shocked at how heavy and sturdy this bracket was. I could see that there was no doubt this would support that 50+ pound monster that I lugged in and up and out and down every spring and fall. Simple to assemble, well finished in a hard baked white enamel (it may even be powered coated- not sure) almost unlimited adjustment holes for the angle the unit will rest at, and a really study tray and frame catch bracket put my mind at ease immediately for both strength and return on investment. I expect this bracket to last for many summers to come. Spend the money once and get it over with.

The primary support brackets - the ones that come out of the window - rust BADLY.

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!!

This ac mount is well made. It was packed well too. My Milgard windows are flush with outside wall. Before purchase, I looked at TopShelf Website. I knew the two feet at base would not touch my wall without a little modification. Each foot is removable and has four holes with rubber cushions inserted. I removed the cushions and attached a piece of primed, painted wood (approx 1 in. pad) using wood screws. I believe the attached wood provides even better distribution of force on the stucco wall. The mount works well and looks good.

Exactly what we needed. Our AC was too complicated to use the manufacturers instructions to install in the window. We had to take it out of the casing, screw the casing into the window, attach the brackets to the casing, slide the unit back into the casing, put it all back together, put the rim brackets on, it was a pain. I thought someone else has had to have this problem, and there has to be a solution out there already, did some research and came across this product. One caveat. BE SURE TO CHECK YOUR EMAILS. The manufacturer will be contacting you to confirm the type and size of windows you have. Id recommend putting that information in the product description. After three cancellations and a poor review from me, I ran across the buried emails in my inbox. After we connected Ernie was great, and even sent this out overnight for the regular shipping charge because of the misunderstanding. At first I was miffed, because Id already read the requirements and had already measured the windows and such, but on second thought was pleased theyd go to so much trouble to ensure you have the correct type of windows. A lot of people dont read the details. NOW FOR THE PRODUCT ITSELF: This product is VERY STURDY & WELL MADE. EXTREMELY EASY TO PUT TOGETHER. SIMPLE TO ADJUST. Two arms rest against the inside of the window frame, the two legs rest against the outside wall and the weight of the unit holds everything sturdily in place. Is absolutely ideal if you have an upstairs window in a rental apartment and cant mar the window with screws and such. For our house, its on the first floor, which Id be hesitant to do if the unit wasnt so heavy. All in all, a WELL THOUGHT OUT PRODUCT. I RECOMMEND IT WHOLEHEARTEDLY - if you have the correct type and size of window.

This Black & Decker bracket is very well made, and we thought it was exactly what we wanted for easy mount and dismount of our tiny A/C unit, which we only use 2½ mos out of the year. Unfortunately, it sounds more like a universal fit than it really is, regardless of the many adjustments you can make for both the interior and exterior wings/legs (half stops for the exterior = wonderful). Though we finally found a place for the gripper feet on the exterior legs to lay flat against our siding, it left the bracket at an incline instead of a decline, which is of course the opposite of what you want with an air conditioner because of condensate concerns. We tried numerous times (literally a dozen different adjustments!) to get it to work, but it was impossible for it to be snug on the frame inside and at the proper angle outside. Plus, it left huge gaps beneath the A/C unit on both sides. Also, we feel it was made for larger units and that this should be noted. We purchased the very popular and best-selling Frigidaire unit here on Amazon, which is tiny and only 40 lbs. It just barely fit (like by a mere half inch) when centered on the bracket, and kept slipping between the vertical legs/supports—to the extent that we went online to look for rubbery bits to apply to either the A/C or the bracket, and then we thought, What are we doing?! This just wont work for us. Amazon processed our return without a hitch. (And honestly, later drilling three holes in the bottom of our vinyl-clad window was absolutely NO big deal—and it left no gaps.) Bottom line: Its well made, and an attractive color (the dark grey). But know that even if you measure all surfaces and areas, and everything looks as though it will be a perfect fit, its still possible this bracket is not going to work for you. However, Id still recommend it if you have a more standard size A/C unit and a flatter exterior surface like brick or stucko. Siding is tough because of the way the rows cut off, and you just wont know if this will work until you have it in your hands for a trial. Thankfully Amazon is good with returns if youre prompt with your trials.

This was such a delightful surprise! I expected screws and hex bolts and all manner of headaches putting this together. It was so simple, I almost didnt believe it. This is top rated by Wirecutter and theyre on the money with this review!

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.

Very easy to put the rack together, but our AC has a bulge at the bottom so had to angle it much lower to accommodate. The rack didnt allow for the weather stripping around our window to seal close completely. All said, its still a nice device to have which makes it easy and safee putting up the AC to the window.
