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

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.

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).

Air conditioner support.

The directions will tell you that the hex bolts are 3/8, and that is even stamped on the head of the bolt. BUT IT IS NOT TRUE!! Only a 10mm wrench or socket would fit them. Even worse, the screws broke during installation and I used my own spares to build. The instructions reference numbers and letters for parts and steps, like you would expect, but the instructions were poorly written. I hope they didnt use Google Translate for the instructions! I did install the product in the end but it was a rough experience and took twice as long as it should have.

Confusing to put together, plan to have extra hand

Theres a discrepancy on the build instructions that states using a 7/16 wrench or socket this is absolutely wrong on so many levels, its metric not standard bolts as the kit I received had 10mm nuts and bolts. It was easy to assemble straight forward but at least include the proper hardware with this universal kit please, or update the instructions because it seems like corners were cut on material cost(s). Once my new ac unit arrives Ill update my review with some video and pictures of what Im commenting on. Get this you wont be disappointed its of great quality looks very nice and powder coated steel. My speculation this will last longer than the ac its going to support!

The connections once completed are solid but the side to side and depth adjustment procedure are unnecessarily burdensome and when you’re done the end of the interior braces have a vertical piece that is in the way of the air conditioner’s side panels

This bracket is good. Easy to assemble and install. But, it left a large gap under the air conditioner that had to be filled with a 2 x 3 and 2 1/4 x 2 1/4 air conditioner foam.

This was easy to install. I did have my 16 year old help me. I needed another set of hands.

Dislike directions. Definitely sturdy. But now my unit leaks a lot down side of my wooden house all day long.
