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

This was easy to assemble. It looks nice from the outside. We live in a second story condo and put it in our primary bedroom. It feels sturdy even with a heavy AC unit on it.

I have an older house with a mix of windows - some with storm window frames, and newer ones without those frames. This bracket will not work on the windows with storm frames because it is designed with the assumption that the sill and stool will be continuous, but in the case of the storm frame, the bracket cant sit properly on the stool -- the horizontal piece in the front -- because the frame gets in the way. Also, the spring-loaded buttons that are supposed to lock the support arms in place do not work in unison. That is, when one button is engaged in a hole, the other is compressed within the frame and off-center from its corresponding hole. The bracket is fairly sturdy, but I am very disappointed overall in its performance.

The buttons were at an angle and didnt line up with the holes on the bracket. Tried our best to finagle them, but to no avail. Happened with both sets that we purchased. Returning.

Good idea, easy to install but didn’t fit our windowsill. It left a gap all along the bottom of the ac, not even tape would help.

Relatively easy to put together, super easy to install, very sturdy. Holds 59 lb air conditioner with no problem. Looks great. Directions are a bit difficult to understand. Has buttons on opposite sides that allow for very fine support arm length adjustment. Only one snaps into place at a time. Finding that in instructions is a challenge.

Easy install and solid support, wont fit my vinyl window track well enough to use.

I tried supports from Home Depot and Lowes but none of them worked with Vinyl windows, they required that you either screw into the window frame or the mount was too far on the inside of the window to allow the side panels to work. This product is very sturdy. No tools required and fit almost perfectly. Leaving a nice sturdy channel to rest the bottom of the air conditioner into. I took one star off sturdiness only because the bottom bracket does have a slight bow to it with the weight of the AC unit. Nothing I am overly concerned about though. Very pleased with the frame and would highly recommend to anyone with vinyl windows and a 10k btu or higher window unit. My windows are 36 wide and this worked great. Note: I had to install the bracket further in with the tabs on the window casing not on the window frame as instructed. There is only about 1/4 inch or so on each side that the metal tabs could rest on the window frame, which the adjustment holes on the sill bracket did not have fine enough adjustment for and I would not have felt comfortable with so little (1/4 inch on each side) holding the AC unit in. So using the foam strip on top of the AC unit and some Duck brand foam (https://www.amazon.com/gp/product/B002GKC2WQ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) it works fine.

This AC support was easy to assemble and install. No drilling required was the best part. This support made installing a 160lb window AC much much easier. Make you measure your AC prior to purchasing this AC support. Take note of the recommended usage. Reach out if you have questions. You may be able to still use it if you have a 2 piece AC.

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 Black & Decker bracket is very well made, and we thought it was exactly what we wanted for easy mount and dismount of our tiny A/C unit, which we only use 2½ mos out of the year. Unfortunately, it sounds more like a universal fit than it really is, regardless of the many adjustments you can make for both the interior and exterior wings/legs (half stops for the exterior = wonderful). Though we finally found a place for the gripper feet on the exterior legs to lay flat against our siding, it left the bracket at an incline instead of a decline, which is of course the opposite of what you want with an air conditioner because of condensate concerns. We tried numerous times (literally a dozen different adjustments!) to get it to work, but it was impossible for it to be snug on the frame inside and at the proper angle outside. Plus, it left huge gaps beneath the A/C unit on both sides. Also, we feel it was made for larger units and that this should be noted. We purchased the very popular and best-selling Frigidaire unit here on Amazon, which is tiny and only 40 lbs. It just barely fit (like by a mere half inch) when centered on the bracket, and kept slipping between the vertical legs/supports—to the extent that we went online to look for rubbery bits to apply to either the A/C or the bracket, and then we thought, What are we doing?! This just wont work for us. Amazon processed our return without a hitch. (And honestly, later drilling three holes in the bottom of our vinyl-clad window was absolutely NO big deal—and it left no gaps.) Bottom line: Its well made, and an attractive color (the dark grey). But know that even if you measure all surfaces and areas, and everything looks as though it will be a perfect fit, its still possible this bracket is not going to work for you. However, Id still recommend it if you have a more standard size A/C unit and a flatter exterior surface like brick or stucko. Siding is tough because of the way the rows cut off, and you just wont know if this will work until you have it in your hands for a trial. Thankfully Amazon is good with returns if youre prompt with your trials.
