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 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.

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.

Strong and it holds in place.

I purchased three of these brackets for use with window ACs ranging from 5000 to 12000 BTU. The bracket does take some time to assemble, then partially disassemble and reassemble once you discover that the legs arent attached to the frame exactly where they need to be to prevent the bracket from sloping toward or too far away from the house. I also noticed that each bracket, even with all bolts securely tightened, seems to lean slightly to one side. causing the AC on it to lean slightly to one side or the other. This is resolved easily enough by inserting a shim or two between the bracket and the bottom of the ACF on whichever side of the bracket is slumping. Note also that there is a gap of a couple of inches between the bottom of the bracket and the window frame that youll have to fill in or seal with something if you dont want horrific energy loss plus bugs, rodents, small birds, etc. joining you on the inside of the house. I think thats just how this style bracket works, though; as the windows in my house are installed flush with the exterior wall, and theres no exterior sill to which I can attach anything, Im moving forward with this item.

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.

Looks sturdy enough for my air conditioner.

Did the job

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.

So far its been working well

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...
