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 have several problems with this window support bracket, first of which is that it came with ineffective hardware. It doesnt have enough washers for all of the pieces, and half of the nuts that came with the package use plastic stoppers which cause them to cap off at a certain point on the bolt when threaded on. This means they cant be tightened down all of the way and would require at least twice as many washers as the kit came with to make the join on these bolts secure in any sense. Second although the kit claims to fit most windows, at the smallest setting for the brackets, the legs still dont have a tight enough hold on my window ledge and are just too heavy for a second story window. They dangle and pull the entire bracket down. Not to mention, the weld for the main support ledge is crooked which means getting the center support in between the main two arms was nearly impossible and tilts the entire ledge at an angle when joined. This causes the screws for the legs to come loose with time. I will be returning this product as soon as possible.

Was able to setup in 30 minutes, Placed parts on a flat service and laid out as if assembled, then followed the instructions. The Leg supports took the most time in the setup, primarily to determine where they should be located. Do think more pictures should be included in instructions reflecting a step by step pictorial, especially for the leg supports.

Im so glad i bought this item. Its my first time installing something of the kind so i was very concerned about the weight and position for our window ac unit, Im glad i didnt have to hope i had done an ok job and just letting the ac unit hang on its own on the window frame...

I personally dont want to leave this unsecured to wind not really easy to install but also not hard. Overpriced for what it is. to be fair though it is sturdy

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

This review covers the drill-less version of the bracket. Make sure this will work with your air conditioner. The bracket arms that extend out are between 13” and 16” apart so edge to edge the feet on the window side of your air conditioner need to be in this range. I first tried this with a 6000 BTU Amana air conditioner but the “feet” on the front of the unit were two narrow so the front towards the window was not supported properly. Then I used it on a Frigidaire air conditioner. The feet on the Frigidaire air conditioners are 2.5 time the width of most other window air conditioners so it rested on the bracket perfectly. The feet on the Amanda were about 1/2 an inch wide. The feet in the Frigidaire were about 2 3/4 inches wide.

Once assembled the bracket is very sturdy, so it does the job its designed to do. However, my experience was pretty frustrating, and I reflected this in my rating. Im a pretty handy person with an architecture and engineering background, and a lifetime of DIY projects, so I dont usually gripe about this sort of stuff unless its really warranted. For the price I paid for this item, my experience should have been a lot better. 1.) Item arrived missing about half the fasteners required for assembly. The fastener pouches were factory sealed, so this wasnt an open box/returned item. I would have returned it because of this, but its over 100 degrees where I live and I needed to install my AC ASAP for the health of my family. So I wasted some cash and a couple hours of my time going out and buying the necessary fasteners to complete assembly. 2.) The manufacturing on this product does not live up to the tight tolerances it was designed with. The metal piece (item 8 in the parts list) that is bolted between the main support arms (items 6 in the parts list) did not fit because when bolted to the main adaptor bracket (item 1 on the parts list), the space between the arms was too tight. It required about half an hour of wedging and jamming to get it to line up to the correct holes. Im a grown man and I struggled with this. A weaker person would have struggled much more. 3.) Its almost impossible to bolt the adjustable arms (item 2 on the parts list) to the main adaptor bracket because the space inside the bracket is extremely tight. These are crucial to the function of the bracket, so leaving them loose is not an option. For something as expensive as this, the design should either make the interior side of this hole more accessible , or the choice of fasteners should have been more appropriate for use in tight spaces.

Since the written instructions for the two-arm, heavy duty version (drilling required) of this bracket are almost impossible to follow, a good installation video is needed, but there are a lot of problems in Alpines installation video. Mainly, the sections showing how to install the connector bar are pretty screwed up - it shows the long hex bar being inserted at different locations. Also, in the section for the final installation (at 2:52 of the video), the connector bar magically disappears altogether. More detailed comments, with many of the flaws in the video, can be found at the YouTube version of this video (the two arm, heavy duty, drilling required version). Alpine did a really sloppy job with this video.

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.
