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 didnt want to pay ninety-nine dollars for this -- but there was no other solution. I must say, when it arrived I was very impressed with the packaging and build quality and my angst over the price dissipated to the point where I could swallow the price. Packaging -- it comes in foam packaging with cutouts for each part so they safely stay separated and undamaged. Build quality -- theres no way this is bending and it looks to be powder coated for a great finish that wont peel or rust easily. Problem: I had to return it though because it wasnt obvious to me that it would add an inch (eyeball measurement) to the overall height of the window sill. This made it impossible for me to fit my AC in the window. Even if I had been able to fit it in, I wasnt sure I liked how the feet were pressed against the bottom edge of my vinyl siding shingle (is that what its called?). I wish there was a way to lower the legs somehow so that I could place them squarely on the top part that is closest to my actual house where it wont be subject to the same pressure. I worried that over time the vinyl siding would crack.

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.

The bracket is sturdy metal. It goes together and installs easily and should work well. The problem with mine is the front support wing lock pin was broken upon arrival and sitting in the bottom of the box. Some of the paint is also chipped, which will cause faster rusting in Seattle weather. I can fix this, but should not have to for this price. I am waiting for a reply from their customer service and hope they will just send a replacement wing rather than having to hassle returning the whole thing. If they send a replacement, Ill be able to increase the sturdiness to 4 stars The leg lock pins do not go into both holes at the same time as some others noted. I thought they were broken, but the instructions note only one pin locks at a time. *Update 7/8/21: The Top Shelf Team was quick and responsive. They replied quickly and sent a new wing to replace the broken one. Kudos and thank you to them. Upgraded rating to 4 stars.

Product is very solid and fits really well into my window frame. Did slightly adjust where the AC lines up with my window so the lip doesn’t exactly align, and some air gaps increased, but that’s because I have an old style house where the side panels don’t line up with where the window slide open. Some rolled up towels were able to seal the gaps. Definitely feel much better about having my window AC above the front of the house, especially if we experience any big earthquakes, I feel like this will actually stay in the window now. Anyways, my product had a slight defect (defects happens even with the best product manufacture design), I reached out to customer service, and they sent me a replacement piece right away. Replacement piece works great. Would buy again.

The first one of these had a couple small flaws in the paint so I returned and it was replaced promptly. This is amazingly study, quality piece of equipment. Assembly is easy and almost intuitive after a quick look at the directions. I usually use smaller 5000BTU air conditioners and have installed in the past without an outside support. However, with a new 65 pound 10,000 BTU unit, I was uneasy balancing it in the vinyl window. Most of the support units require drilling holes in the outside window sill, but this unit does not, a real plus as I need to remove it in the fall. This was an excellent choice. I felt like I could adjust the unit in the window, knowing it was well supported and safe. Recommend!

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.

Ive tried allot of different style.. even made some myself. As a retired engineer this is far above anything on the market

I struggled for hours, trying to figure out exactly how to position the bracket. I then emailed the company and received a prompt reply, along with photos which depicted the tabs positioning better than the product insert or the online video. The companys owner asked if my windows are wood (they are) and noted that the bracket works better with vinyl or aluminum windows. I was able to establish a satisfactory, though not perfect, installation, which required slightly bending the brackets base against the inside window trim, which permits the air conditioner to tilt slightly to the outside for drainage. As with most window air conditioners, some filling in with foam is also necessary, but this is not a difficult task.

First, this went together very, very easily. I had it assembled, adjusted, and in the window in a few minutes. Sliding the A/C unit in place was very easy. But a couple thoughts on making it a bit better 1) The alternating pins are very clever, but need to be called out in the instructions. I thought something was wrong for a moment, until I realized how it was walking into place, moving one detent at a time. 2) its not clear in the instructions how the wings that hold the inside of the window frame are supposed to fit up against the window frame and trim. I ended up extending the wings as far as I could within the window (based on the flat portion on the bottom), and let the tabs reach as far as they could. 3) I padded the support against the window with some foam, and put some of the foam that came with my A/C unit (meant to be applied to the window sill) to the shelf in a few contact points to reduce the amount of metal-to-metal contact and vibration (its noticeably quieter, now).

Fit great, supports our large ac. We did install a block of wood between the frame and the window, and did end up drilling two small holes for the wings but I didnt mind - worth it for the peace of mind.
