Nope, you don't need to drill anything to install the Top Shelf TSB-2438 AC bracket. According to the manufacturer, it supports up to 225 lbs and you can set it up in just a few minutes, all from inside your room. You just attach the wings and legs, position it in the window frame, and you're good to go.

It works for double or single-hung windows between 24” to 38” wide, with wall thicknesses ranging from 6” to 12”. Just make sure you’ve got at least 10” of space below the window. However, it's not compatible with slider, crank-out, casement windows, or certain wood windows like the Andersen 400 series, and it doesn’t work with slide-out A/C units.

The manufacturer says it's made from rustproof, powder-coated steel, adding some extra durability with its 4-sided enclosed legs and sturdy steel tabs and pins.

Our research shows that people generally find it pretty easy and quick to install, often just taking 5-10 minutes. Users like that it snaps together without the need for screws, nuts, bolts, or any extra tools. One person even commented how much simpler it made installing their AC unit without having to balance a heavy appliance.

On the flip side, a few folks have raised concerns about its long-term durability. Some have mentioned that the paint started to flake off, leading to rust over a few years. There are also some issues with compatibility, especially with non-standard or older window frames.

A few users mentioned that the rubber parts meant for stability weren't enough and they had to add more materials to get a snug fit. One user even needed to modify their window quite a bit to get the bracket to fit, which took more time than they expected.

So, while the Top Shelf TSB-2438 is generally liked for its easy installation and sturdy build, you should double-check that it’s compatible with your window type and be aware of potential long-term durability concerns.

The Top Shelf TSB-2438 bracket is designed to be pretty versatile when it comes to fitting various window sizes. According to the manufacturer's description, setting it up is pretty straightforward—just attach the wings and legs, pop it in the window, and you're done.

From what we've found, many people appreciate the simplicity of the installation. One person mentioned it took them just about 5 minutes, thanks to it snapping together without screws, nuts, or bolts. Another person said it securely holds their air conditioner, making it easier to install without needing a second pair of hands.

However, it's not always a perfect fit for everyone. There are some cases where users faced challenges, especially when dealing with specific types of windows. For example, someone had trouble fitting the bracket on vinyl siding and newer-style windows, finding it tricky to get it to sit properly.

Another person noted that the rubber ends came off easily, requiring them to add some extra foam to fill in the gaps.

So, if your windows match the specifications the manufacturer provides, the Top Shelf TSB-2438 bracket should work well for you. It's known for its sturdy design and ease of use. Just keep in mind that you might need to do a bit of adjusting if you have unique window features.

The Top Shelf TSB-2438 AC Bracket can hold up to 200 pounds, according to the manufacturer's description. That's plenty for most standard window air conditioners.

But, there's a bit more to consider. If you've got vinyl siding on your windows, you might want to be careful. Our research found that the bracket's legs can sometimes cause deformation or cracking in vinyl siding. In fact, one person even returned it because of potential damage risks to their siding.

To avoid this, you could try adding some protective padding between the bracket and the siding. It'll help spread the load and reduce the direct pressure, which should help prevent any damage.

It's also worth mentioning that the bracket is generally easy to install and sturdy. Still, make sure your specific window and siding can handle the weight and pressure before you install it.

That way, you can avoid any mishaps and ensure everything stays in good shape. In short, while the Top Shelf TSB-2438 AC Bracket is strong and user-friendly, just double-check your window and siding situation to avoid any issues.
