Top Shelf TSB-2438 Universal Heavy Duty Window Air Conditioner AC Support Bracket -Holds Up to 200 lbs., No Drilling or Tools Required, White

I purchased the Top Shelf TBS-2438 air conditioner support to hold a very large unit. Assembly and insulation were easy. It took a few minutes to adjust the position of the supports against the exterior wall, to accommodate the wall thickness. However, you should only need to do this once, unless you plan on disassembling it each time you use it. Since I have vinyl windows I was concerned with damage that could be caused by resting the air conditioner on the window frame and holding it in place with the upper sash. The thickness of the metal and painted finish are better than I expected. And if and it is very sturdy, if you assemble it correctly and make sure it is level. I am pleased with the product and can recommend it.

This ac mount is well made. It was packed well too. My Milgard windows are flush with outside wall. Before purchase, I looked at TopShelf Website. I knew the two feet at base would not touch my wall without a little modification. Each foot is removable and has four holes with rubber cushions inserted. I removed the cushions and attached a piece of primed, painted wood (approx 1 in. pad) using wood screws. I believe the attached wood provides even better distribution of force on the stucco wall. The mount works well and looks good.

Top-Shelf is fantastic! I highly recommend Top-Shelf air conditioner supports. I purchased two of the Top-Shelf units and these have saved me a loads and loads of frustration in installing my air conditioners every summer. Previously, the weight of each air conditioner was precariously pressed against the top window pane while my back was killing me trying to prevent them from toppling out the window during installation and removal for the fall and winter months. The installation of the two Top-Shelf window air conditioner supports was very easy – although initially it looked a little confusing. As there are very many styles of windows, my reinstalled windows did not need the sliding left and right wings that come with the kit as the bottom of my reinstalled windows adequately support my air conditioners. As the instructions specify, there is no requirement for drilling or using additional tools, fasteners or hardware. They even included rubber feet for the foot brackets that press against the house siding under the air conditioners. However, what I did need to purchase extra were a couple of packages of Frost King Air Conditioner Weatherseals (1 1/4 x 1 1/4 x 42 available on Amazon). This was necessary to fill in air gaps under the air conditioner – both inside and outside of the house (which I would have needed anyway with or without Top-Shelf).

Xtra smooth Quality

Extremely sturdy and easy to install BUT needs some modifications if using with an AC requiring to install the cabinet then the AC itself. I used 2 pieces of 3/8 thick aluminum I bolted to the far crossbar , then I could install the cabinet (bolted to the crossbars). I would suggest the manufacturer to offer this modification as an option. Fits tightly and very nicely. Required very little weather stripping. For all other window ACs, can be used easily. Just check that your windows are compatible with this shelf: go on the web site of the manufacturer: there are some good pictures. By the way the instructions are not well written.

I really a sturdy product, and very easy to install. Only thing is I wish I can get the shelf arm closer to the outside wall. Because the adjustment arm hole in 5ge last one. The arm still fall from touching the outside wall. I need the pull in my windows air-conditioning more in to the window, so the both outside support arm can touch the outside wall to support the air conditioning. That is why I give it a 4 Stars.

This shelf does hold an air conditioner; mine held a large unit. It wasnt incredibly difficult to assemble. That being said, it did leave a gap at the bottom where outside air could easily infiltrate. I also found damage on my sill. Additionally, The water ran out of my unit down the closest leg and painted my brick wall white. It also rusted away all of the paint on one foot and introduced rust on the other foot. I also had difficulty keeping the pads in while installing the mount. Its a good concept but the product needs a little more quality control.

It looks like a high-quality item, but it did not work for my window. Build quality is very good, almost over-engineered. The only issue that I have with this bracket is that for the type of window this would work for, you probably wouldnt even need such a heavy-duty bracket, since windows with adequate ledges can bear the weight of an air conditioner far better than those without. For those types of windows, there are far cheaper options (shims, 2 x 4s, etc) that would do the job just fine. Also, based upon the description and my measurements, this *should* have worked for me, but unfortunately, it did not - my ledge was just a hair too shallow. This possibility is something you might want to keep in mind, because returning it will be really inconvenient, should you need to. I do wish this would have worked. With this bracket, you could put a really big air conditioner in your window and rest secure knowing that it would be well supported. If a bracket is required by your HOA or apartment complex, this is the one. It really is a very nice bracket. Even though I had to return it, I give it five stars overall.
