    This seems pretty sturdy now that it is installed. But, 2 of the screws snapped in half while installing. My husband traded out the screws that came with it for deck screws and at this point, every thing seems good.

    From what I can see, the materials used in this project seem sturdy and durable enough to withstand the elements in the long run. However, accessing and aligning screws and nuts in certain areas can be challenging due to design flaws. Additionally, the instructions only provide a generic list of necessary tools such as wrenches and sockets without specifying the required size. This, along with the inadequate design, can result in wasted time and effort when constructing what should have been a relatively simple device.

    I decided to order this AC support bracket because I did not want to drill into my new window and frame to install the window AC it took me 2 days and a bit of figuring out to complete the install because packaging is missing supplies (14 washers needed but only 6 provided) and the instruction pictures arent very clear either although the hardware store is 1 block away it took 2 day trips because they closed on me so had to go back the next day. the screws are specialty screws and regular washers will not fit so had to go back to get the whole new set (screws and washers) to complete the install and just a side note if you do not have a handyman suitcase with different tools in it, you ll not be able to secure the screws either as unlike other DIY sellers will provide you with the handy tool in packaging (if you need to use a specialty tool for the screws and not just a regular screwdriver) conclusion if I wasnt gifted the new large window AC id not bother with this costly bracket but returned it after discovering it was not a straight forward few minute install ..

    Confusing to put together, plan to have extra hand

    One of the hardest things I have put together. Instructions were not clear (noted, I received different instructions from someone else’s photo…mine was missing half the labels and had an awful description of which nuts and bolts to use). It’s definitely sturdy, but no more sturdy than a regular bracket. I don’t understand why these are more than double a good regular bracket. But I paid because I didn’t want to drill and there were zero cheaper options.

    We don’t assemble stuff very often so this took us a while. We used the written directions along with the online video. You need both. The first step where you attach the brackets is misleading because you should anticipate that they will need to be unscrewed and repositioned to get the angle right. That takes time and tinkering to figure out where they should go. But once you get it right this is a nice piece of engineering. Tension holds it in place and creates a sturdy shelf for the air conditioner. But also be prepared for a big gap at the bottom. It needed to be stuffed with 2x1 inch foam (the black part in the picture). We also used side panels to help cover the sides and to stuff any smaller gaps. Once it is put together we won’t have to do it again and installing the air conditioner in the future will be a breeze (pun intended).

    I purchased the drill-less bracket and its useless. Normally I rely on the metal nubs that hold the window accordion and jut out of the bottom and top of my AC unit to provide leverage against the sill and hold it flush against the window. Since this bracket lays flat across the whole sill theres no way to let the nubs on the bottom of the AC lock in anywhere on the sill or bracket, instead they just balance on top of the bracket leaving about 1/2 of space for air to get in beneath the AC. Not only does this mean you would need insulation foam to fill this gap, I also live in a third floor NYC apartment above a daycare. I do not feel comfortable mounting an AC unit on this bracket if its just going to balance there, because lets just say the rest of the manufacturing doesnt instill confidence in its sturdiness. This bracket may work for someone who just needs to mount an AC above their backyard with low consequences for it falling (youll still need to buy insulation), but its not gonna cut it if you live in an apartment and a falling AC could hit someone in the head.

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

    Easy to assemble. The pieces were too big to anchor the bracket in place, so I had to go to Home Depot to get some. That wasn’t an issue. Only issue I had after assembly, and trying to install it the the window was that no matter how hard I tightened with my drill set, the bracket wouldn’t hold shape. I had to drill more bits into the racket itself to get it to sit correctly on the concrete on the outside wall. It was the only way I could get it to stay how it needed to be in order for it to hold its shape.
