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

Exactly what I wanted. I didnt want to drill holes in the siding but needed a window unit for my garage. It holds a 12000btu unit very well. It is capable of holding even a larger unit. Most importantly NO HOLES!

Did the job

It is a good, sturdy bracket, especially at that price. It takes a little bit of skill at assembling things to put together and was a bit more of a project than I anticipated, but I had it done and set in about half an hour.

Pros: Its nice and really heavy duty. I can see this lasting a long time. It also has a built in level which was handy during installation. Cons: The setup 1) The paper instructions are not helpful at all. Thank god they had a setup video. 2) It is not easy to get the angle/Position of the arms correct. You have to unscrew the bolts, reposition the arms then screw it all back together again. You have to do this over and over again until you get the angle correct. Other AC Unit support brackets did not have this. You just pressed a button on the arm and it lets you reposition it.

Window air conditioner.

I have used the one leg and this version. Installed a large 18.000 BTU unit with this item. Not too many parts, decent directions. I had to fiddle with the settings to get it right (VERY weird customer window so harder). Best part was the level-allowed me to gauge EXACTLY when i got everything right. Before the AC unit went in, I hung my 165 pound body on this to show my customer how strong it is. Dont screw around, an AC can break the glass in a window, and/or bend or warp your window. Instead place it on this support. It will protect your window from rot (same customer had wood under their last unit-this job included rebuilding the window ledge). The outside foot will protect most house cladding-even cedar shakes. Ill never install a window unit that weighs more than 45 pounds without the one arm or two arm version. Check your ac unit weight and buy one of these. It will look professional. (I am a Home Improvement/maintenance contractor).

Do yourself a favor, go to YouTube and watch the instruction tutorial for this. The instructions are a nightmare to understand, and there are random pieces included (anchors that are different sizes and wouldn’t fit into the holes you are suppose to drill with a VERY specific drill bit). I was trying to start the install of this based on the directions alone and I was VERY close to hiring someone. Then I watched the video tutorial that was about 2 minutes long and it took me about 10 minutes to get in (probably would have gone faster, but I have a VERY curious 3-year-old). Otherwise, it does what it is suppose to, ad helps to support our 6500Btu 58lb air conditioner.

I recommend the double support bracket design over the single one as this will hold the AC unit securely. There were a few quirks about the installation. The bubble level indicator doesnt snap in place, it will just fall out. You would need to glue it in or something if you needed it. The instructions show you want to screw the cross brace with the long hex bolt behind the short phillips bolt. When you do this, the support leg binds with the phillips bolt when it collapses. I flipped the positioning of the long hex bolt and short phillips bolt, you get a support leg that can swing freely while still having the cross bar attached at two points. I use this bracket to support a window unit in my roof top tent, and it works perfectly.

This bracket was purchased to hold a 80lb Kenmore A/C unit. We came into two issues. Our first issue was that the surface of the mount is slick metal. When the A/C unit asks with installation to have a slight outward tilt so that condinsation call fall outside the window. We noticed the unit was also built metal so it wanted to slide. There is no backing plate to hold in place and no items such as rubber spacers to help A/C from sliding around. So we took a board and cut it to the size of the A/C unit and screwed it to the bracket to give it less a change to slide. The next issue was the mounting screws. We followed the directions and pre-drilled the holes to mount to the window. Once installing the screws with a half dead almost powerless drill the bolts snapped. Right where the threads start. We decided to try another screw and once again it snapped. We then went to the hardware store and purchased the same size standard screws for 35cents each. We then installed bracket with no problems. Putting the provided screw next to a standard screwed we purchased you can right away notice the quality difference of the metal being used. The strength of the bracket itself seems strong. Once everything was installed I put some good amount of my weight on it and it held strong. For the price and quality I would have to say you should try another product or plan to grab some quality 35cent screws and figure a way to keep unit from sliding.

We don’t assemble stuff very often so this took us a while. We used the written directions along with the online video. You need both. The first step where you attach the brackets is misleading because you should anticipate that they will need to be unscrewed and repositioned to get the angle right. That takes time and tinkering to figure out where they should go. But once you get it right this is a nice piece of engineering. Tension holds it in place and creates a sturdy shelf for the air conditioner. But also be prepared for a big gap at the bottom. It needed to be stuffed with 2x1 inch foam (the black part in the picture). We also used side panels to help cover the sides and to stuff any smaller gaps. Once it is put together we won’t have to do it again and installing the air conditioner in the future will be a breeze (pun intended).
