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 two of these units for window mounted air conditioners. Assembly was simple and each fit the window opening fairly well. Due to the difference in window frames, perfect adjustment was a bit off but nothing that would cause me to not recommend the product. As we are in the Northwest, we only need air about 3 months a year so being able to remove the units and mounts during Winter is really important. These are great products that secure the window air conditioner without any need to drill holes in your house.

We are so happy with this product. Sturdy, Strong, Reliable, quick to assemble and very easy to use. Holds the air conditioner in the appropriate position at the appropriate angle. The feet that rest against your house/apartment/office have silicone nobs as to not damage siding. Another great feature about the feet is they are flexible to accommodate different types of siding. The legs have several adjustment options for any angle needed and securely lock into place. I definitely recommend this product if you plan to put an air conditioner in an upper storey home/apartment/office window. We tried several others that werent terrible but none compared to the sturdiness and peace of mind this Bracket provided. Youll also notice your air conditioner will run quieter because it is sturdy.

Impressed by sturdiness and ease of use. More expensive than many alternatives, but worth it for the strength and ease of application.

I had my old windows replaced with vinyl after air conditioner season last year. When I recently went to install my ACs, I discovered they no longer would mount the way they used to without the support of the old storm window housing along with not being able to drill into the new window sash or sill. I had no idea what I was going to do until I saw this product. It is absolutely perfect for my application. It took less than two minutes to put the pieces together and get ready to install. I was impressed with the sturdiness of the bracket and the way it locked down by moving the legs closer to the exterior of the house one click at a time. By the time I was ready to hoist the AC onto it, I had 100% confidence the bracket would stay firmly in place. As an added bonus, the thinner layers of packaging material make for excellent flexible insulation around the areas where gaps will ocur below and to the side of the unit. Also, because I have vinyl siding, I used some of the styrofoam to put between the feet and the house.

This unit is identical to a Black and Decker unit being offered on Amazon right now. The Black and Decker offer provides a very helpful instructional video. Watch the B&D instructional video to know how this thing works. I found the B&D video AFTER installing the shelf (and I bought it two years ago). I realized it is not for my type of window (double pane), but it still works for my situation, with some adjustments and customizations.

This is overall a very good product, from the standpoint of support and security, once you learn to adapt it to your particular situation. I had to improvise, since the unit for which I had bought it had under-unit channels for the accordian flanges that made it impossible to fit the only possible place in the TopShelf. So I had to have the a-c sit totally on top of the Shelf in order to bring the window down behind the top rail rather than in front of it. This required some extra carpentry and insulation and the making of extra panels to keep out external air. Still, my major concern is the security of the a-c, and in this it doesnt fail. Our old farmhouse window doesnt have any added stress with TopShelf

I now have four of these brackets. They are very useful for installing any window air conditioner. Even the smallest A/C units weigh 30-40 lbs and that is a lot of weight to be moving around in awkward ways. I first bought one for my daughter after she dropped her A/C out her back window. It is important to visit the Top Shelf website to see if the unit is compatible with your window and wall thickness before purchasing. You dont need to use any fasteners with it but there are two holes that can be used to screw it to the window frame and I have used a couple of screws to attach mine. Although the price seemed a bit high to me at first, after seeing how inferior some lower cost units were in comparison, I think they are a good value.

This was the easiest AC bracket I have ever installed (took me like maybe a minute or two), and my AC is definitely not going anywhere. Im totally inept when it comes to assembling anything, even with detailed instructions, so this bracket was such a pleasant surprise. Well worth the money.
