    The directions have you assemble things in a weird order that makes assembly very difficult. Also the side bars have to stick out a minimum of four notches cause they hit they each other and can’t go any closer. Also the metal is slippery and the ac unit moves easily, maybe if it was textured it would be a little more stable.

    We bought this for a larger air conditioner and it sat around past its return time due to the fact our air conditioner was first lost and then the replacement was damaged so by the time we went to use this we found that it was missing a part. It was past the return but amazon refunded us anyway and we sent it back. Seemed like it would be pretty heavy-duty and sturdy. Assembly looked to be a little more involved than I thought but who knows?? It may have been easy if all the parts were there.

    I used this bracket instead of the bracket that came with my new window air conditioner because it was installed in a metal building with metal casement around the window. I needed a bracket that was no drill as you cant drill into the metal window sill. We had to attach a piece of wood to the outer support that sits against the building. Once that was done the install was very easy. Highly recommend this product if you cant drill into a window well, such as with my metal building.

    Confusing to put together, plan to have extra hand

    Good idea but couldnt use because the lower rail (holds the accordian sides) on the a.c. unit has to fit in the window groove. With this brace it raises it way above where it should naturally fit.

    Pros: Its nice and really heavy duty. I can see this lasting a long time. It also has a built in level which was handy during installation. Cons: The setup 1) The paper instructions are not helpful at all. Thank god they had a setup video. 2) It is not easy to get the angle/Position of the arms correct. You have to unscrew the bolts, reposition the arms then screw it all back together again. You have to do this over and over again until you get the angle correct. Other AC Unit support brackets did not have this. You just pressed a button on the arm and it lets you reposition it.

    The hardest part about installing this bracket was drilling the holes - but that was because of how I installed it. I wanted my AC unit outside of my window, so I could still shut the window. I did this by creating a plywood baffle that I could insert inside the recesses for the screen. I removed the screen, put the baffle in, then used putty tape to seal it up around the edges. To mount the AC unit and bracket this way, meant I had to drill and mount the bracket on the outside brick/block sill of my window. So with some research, I settled on using some carbide bits to drill with, and special blue anchor screws. I quickly found that: a) you want to drill the block dry b) you want to periodically use canned air (or a compressor) to blow out the hole as it fills with dust If you dont do those steps - you end up with the drill only going so far, then not going any further. So drill, blow out the hole, drill some more, etc - until you get to the depth needed. But other than that difference, I followed the instructions just as they were written, and things went together really well and fast. Ive had the bracket up for about 2 weeks now, and it works great. It only took a couple of hours to install (I took my time, as I didnt want to mess up the block), then a few more to make the baffle (a week or so later, I caulked it, painted it, then re-installed it properly - but I did use it for a week without all of that). The only other extra thing I did was add a couple of L-brackets to the holes, to keep the unit from potentially sliding backwards. Overall, the install turned out great, and Im very pleased with the product.

    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.
