Alpine Hardware Premium Heat Pump Drillless Drill-Less Window Air Conditioner & Heat Pump Bracket - Window AC Support - Supports Air Conditioners Well Over 200 lbs. - No Drilling 2023 Model

I recommend the double support bracket design over the single one as this will hold the AC unit securely. There were a few quirks about the installation. The bubble level indicator doesnt snap in place, it will just fall out. You would need to glue it in or something if you needed it. The instructions show you want to screw the cross brace with the long hex bolt behind the short phillips bolt. When you do this, the support leg binds with the phillips bolt when it collapses. I flipped the positioning of the long hex bolt and short phillips bolt, you get a support leg that can swing freely while still having the cross bar attached at two points. I use this bracket to support a window unit in my roof top tent, and it works perfectly.

Took over 1hr to put together then once everything was good, we sat the ac on it, in hopes the whole thing didnt slide off the window Frame because was holding it from shifting sideways. The ac had huge gaps on the under part where it sits on the frame and the window. Horrible

I live in an RV. I CANNOT DRILL INTO MY WALLS. This support is perfect for RVs.

I loved the product very much except the video does not match the paper diagram.

So far its been working well

Good idea but couldnt use because the lower rail (holds the accordian sides) on the a.c. unit has to fit in the window groove. With this brace it raises it way above where it should naturally fit.

Sturdiness of brace without using screws or nails!

Dislike directions. Definitely sturdy. But now my unit leaks a lot down side of my wooden house all day long.

If youre going to have a window AC unit, you probably need a bracket. This one seems very sturdy for its size, and is doing the trick in holding up my AC. Its not as easy to install as a simple 1-2-3 and there it is. It requires a drill and some technical expertise. Also, in order to fit snugly against the outside wall, you may need further bracing with wood wedges or similar (the shape of my exterior wall required two nearly 3 blocks to achieve level). Read the instructions through before starting installation. You dont want to get stuck halfway through the job with nothing in the open window! I had help from my dad, who thankfully knew better than to start hanging the bracket without taking measurements and cutting the necessary wood wedges (not included!). The integral levels in the arms are really useful to make sure that your AC unit tilts very slightly to the outside and drains away from the window. Once screwed in place, I assume that the bracket will be staying permanently, although Ill put the AC in storage come winter.

Looks sturdy enough for my air conditioner.
