Alpine Hardware Premium Heat Pump Drillless Drill-Less Window Air Conditioner & Heat Pump Bracket - Window AC Support - Supports Air Conditioners Well Over 200 lbs. - No Drilling 2023 Model

The unit was difficult to assemble. One of the supports that goes against your house doesn’t hold up and slips off the house. In no way was this stable and after many attempt to “make it work” we threw this crap in the trash

Great for window a/c of any sixe.

The Alpine Hardware Universal Window Air Conditioner Bracket may work in some cases but it has some serious design flaws and was completely useless for me. Installing a window unit in a garage workshop, I thought the bracket would provide solid support. The first problem that the long screws that connect the legs to the platform are impossible to tighten enough to keep the feet against the outside wall. The legs are just enough narrower than the platform arms that the legs swing free. I was concerned that vibration from the unit would cause them to fall and the weight of the AC would cause it to fall outside, ruining the AC and the window frame. To fix that I made a trip to the hardware store and bought four sets of screws, washers, and lock nuts. That at least kept the legs in place. (See photos) The next major flaw is the frame causes the AC to sit ½” above the bottom of the window frame. That means you’ll need to stuff a lot of foam (not included) to seal the large gap underneath the AC unit. The final flaw is that there is no simple or obvious way to attach the unit to the bracket. Normally the AC came with L-brackets that attach it to the windowsill, but the brackets raised everything so far above the sill that the included brackets wouldn’t reach. The side curtains aren’t sturdy enough to hold the AC in place so a bump to the front or back of the AC would send it crashing to the floor/ground. Rather than make another trip to the hardware store to work around the problems with the bracket, I cut a shelf for the sill from a 2x4 and build a small frame outside to help support the unit. I made it wide enough to attach brackets to keep the AC in place. If after reading this you decide to purchase this bracket anyway, be sure to watch the assembly video several times. It will save you a lot of trouble. The one-page, tiny print instructions in Chinglish are difficult to read and understand and they do not follow the “simple” steps shown in the video. Any product that, out of the box, requires that many updates, fixes, and work-arounds is not worth the time or the money.

I needed a drill-less bracket for my AC and chose this item. Although you dont need to drill the bracket into your outside wall you still need a handful of tools to assemble the bracket itself properly. The instructional video has a lot of unnecessary steps which will require you, as shown in the video, to make constant adjustments to the bracket. For an instructional/installation video there is way too much trial and error. The first step of the video asks you to measure the distance from the outside wall to your window frame and by the end completely ignores that measurement as they adjust the bracket based only on it being level. The measurement and initial placements of the support legs they ask you to do are completely unnecessary. The video itself readjusts the support legs 3 times in order to install the bracket correctly. If you purchase this item I would ignore the video and only adjust the bracket so its level to your window frame. Constantly readjusting the legs is a pain especially as you have to go back and forth with tightening/loosening screws with pliers.

I use this for a small window AC unit on my molded fiberglass RV. I had to use different holes for the legs due to the rounded shell to make it level. Works great. I have no fears this will come off during use and destroy my AC unit. Once set up it is super fast and easy to install and remove. A bit pricey but worth the peace of mind.

The brackets are sturdy-ish, and the hardware isnt the highest grade. But what can you expect for this price? For what it is, it does the job and does it well. Although, install was a little bit confusing due to the poorly translated instructions. I mean, you shouldnt really need to rely on the assembly directions 100% because most can look at it and see whats going on. But I found myself scratching my head a few times after reading the instructions and trying to interpret what it is exactly they want me to do. To mount to the sill, I had to utilize my own hardware, because the provided hardware stripped out (big Phillips head screws for securing to sill plate) after one attempt to drive it into a pre-drilled hole. So, to sum up; -good brackets -not so good hardware -unclear instructions -reletively easy to install despite instructions -sturdy -versitile (comes with adapters to help install over larger sills) If you use your own hardware (to mount to sill only, assembly hardware is OK) then youll be happy with this product. They just need to throw in 2 different sill mounting screws that are a different type of drive (think Allen or Star bit; something less suseptable to stripping) then this will be a 100% solid kit.

We installed this on our RV to hold a window unit. It worked great, and even survived a direct hit from hurricane Ian at a category 4, it held strong with the unit in place. Hated spending $75 for it, but wow, cant complain now.

Wish this had some adjustability to widen out. Still works very well and gives great peace of mind as A/C is on second story. Some bolts are a little tricky to reach and you may have to press legs up to tighten after A/C installed. Overall very pleased. Its very heavy duty. As others have said watch the video and it will help. Probably took about 1/2 hour to install.

I loved the product very much except the video does not match the paper diagram.

As the title states, this is one of the worst purchases I have ever made. From a design and metal quality standpoint it’s fine, but trying to put this thing together took literally hours, and that was with two people. The included directions might as well not exist, and the video for it is also an absolute disaster, it should banned from YouTube. There was not enough hardware included to build it properly, so I was only able to use 75% of the included screwsolts. I have absolutely 0 clue what its actually doing in my window right now or if it’s even really holding up the air conditioner. I was able to eventually cobble it together, but that was only after taking it apart and putting it back together about 5x... Both the directions and the video show you how to build the item, and then in the following steps essentially tell you to completely take it apart again. • If you hate yourself enough to buy this item, or you are really desperate and live in an apartment like I do where you can’t readily drill into your windows, I advise watching the video IN FULL (don’t bother reading the directions they were written by someone with wet brain), from start to finish, several times.... And while building this thing, if you find yourself with not enough hardware, pray. Just pray and believe and hope that this thing will stay together and not come crashing down and take out the persons AC who lives below you.
