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

So far its been working well

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.

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 AC bracket is heavy duty and well constructed. Instructions are a bit confusing and the support legs dont stay in place without an additional screw to hold them up. Im not sure if this is my fault because I cant follow the instructions as my window doesnt look like either of the pictures. But I made it work and I feel that it is sturdy.

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

Ive got two of these. Im not unhappy with them overall, but they are quite difficult to set up. The feet have some trouble connecting with any exterior wall that has siding (which is pretty much every wall). The only way I can get the feet to connect with the wall is if the feet are positioned very inward, but then stability is horrible. Thats the main reason for the 3-star review. They work, but they take some fiddling and you for sure have to screw them into the windowsill directly. They come with spacers to help line up the screwed surface with the window frame so your A/C doesnt sit tilted inward. The provided screws will work for one install, they strip on the heads very easily, but they are a standard size so your local hardware store will have replacements for next year. Also, word from the stupid, careful not to pinch your fingers in this as it does fold completely and with zero resistance so it can collapse (when not mounted) and pinch your fingers easily. Its also very heavy and so the pinch has a real bite to it.

In short, this wont fit windows with an outside ledge that extends farther out than the rest of the exterior. It seems that an exact angle is needed between the two arms to provide support, and the window ledge prevented that from happening. The rubber pad wanted to rest exactly on the bottom of the ledge and couldnt get any support without immediately falling. I live in a century-old brick building where each window has a stone ledge that extends out about three inches on the outside, and it about 4 inches high. No matter how I positioned this bracket I could not get the rubber pad to rest properly on the building. I repositioned and re-drilled three times but no amount of adjusting would let the rubber pad sit properly. All my measurements were correct from the listing and the directions, however because of the ledge none of the holes on the horizontal part of the bracket would allow me to mount it properly. It seemed that I needed the horizontal arm to be a little longer with one more mounting hole for me to be successful. The bottom arm has a metal piece at the top that juts out and that prevented me from using any of the holes. I assume this is because it needs a certain angle to provide support, however none of the angles or holes worked for me. Three stars because it seems like a really quality product, but I feel like ledges are fairly common and I expected this to have no issue. ---------------------- A tip for everyone: Also they have a YouTube video with installation instructions that is worlds better than the included directions.

At the end of the day, this have proven to be the solid support that I sought. The description on Amazon is at best confusing if not inaccurate. I bought the “medium duty” dual-armed bracket for a 12,000 BTU LG air conditioner. The box says it is “light duty” and, in one place, says: “supports up to 80 lbs., typical range 5,000-10,000 BTU,” but the label on the box says: “to 12,000 BTU.” It is very sturdy and easily supported by 85-pound unit (installed correctly). The installation instructions are incomplete and poor, but since I have previously installed two single-arm support brackets from another manufacturer (with better instructions), I had little problem. The biggest error/omission in the instructions is the failure to adequately address the need to level the horizontal arm by adjusting the point on the horizontal arm where one attaches the angled bracket (that presses against the exterior wall). (The instructions seem to presume that the attachment point is at the far end of the horizontal arm, in conjunction with bolting on the bracket that connects the two horizontal arms, but this is WRONG for any but the very thickest house wall. This explains why some comments talk about “hanging” angled arms—they were simply installed incorrectly, probably because of the inadequate instructions.) For most wall thicknesses, the angled bracket must be attached several holes before the end, and this point of attachment may have to be adjusted several times as one trial-fits the air conditioner so that the horizontal arm leans slightly down so that condensate flows out rather that in. This problem is compounded by that fact that an insufficient bolts are provided for the connecting bracket if one attaches the angled arm at some other point on the horizontal arm. The screws supplied stand up perfectly well if one uses a correctly sized Phillips head screw driver.

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

Sturdiness of brace without using screws or nails!
