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

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.

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

If youre going to have a window AC unit, you probably need a bracket. This one seems very sturdy for its size, and is doing the trick in holding up my AC. Its not as easy to install as a simple 1-2-3 and there it is. It requires a drill and some technical expertise. Also, in order to fit snugly against the outside wall, you may need further bracing with wood wedges or similar (the shape of my exterior wall required two nearly 3 blocks to achieve level). Read the instructions through before starting installation. You dont want to get stuck halfway through the job with nothing in the open window! I had help from my dad, who thankfully knew better than to start hanging the bracket without taking measurements and cutting the necessary wood wedges (not included!). The integral levels in the arms are really useful to make sure that your AC unit tilts very slightly to the outside and drains away from the window. Once screwed in place, I assume that the bracket will be staying permanently, although Ill put the AC in storage come winter.

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

Solid product, suggest revision of sizing instructions. Would have been helpful to test size before tightening all bolts.

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.

Took over 1hr to put together then once everything was good, we sat the ac on it, in hopes the whole thing didnt slide off the window Frame because was holding it from shifting sideways. The ac had huge gaps on the under part where it sits on the frame and the window. Horrible

The hardware seems quite sturdy. With the two support beams it is a lot more stable than the single support beams most similar air conditioner brackets have. I haven’t used it long enough to know how it will hold up. The installation instructions are definitely lacking. There are parts included that are not in the instructions. There are numbers pointing to parts in the diagrams that are not in the list of parts that should show what the parts are that the diagram points to. Sections of the instructions I never did figure out. Then some definite errors. Instructions said to use a 7/16 inch socket. That is too big, use a 10 mm socket instead. Instructions said use a 5/32 inch drill bit. Too small, even in soft wood trying to put the screw in started to strip the head almost immediately. 3/16 inch drill bit works much better.

Confusing to put together, plan to have extra hand

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.
