A/C Safe Universal Light-Duty Window Air Conditioner Support Bracket for ACs up to 80-lbs to Protect and Support the Unit and Window Frame

The components here are solid and it goes together pretty simply. I was hoping to use it for a bay window. Needless to say it doesn't work too well for that type of installation without some modifications.

Installed it on a second story window unit installation worked well

GENERAL: Manufacturing a universal A/C support bracket is difficult at best so be prepared to modify or replace the nylon support pieces if you consider using them at all. I used the metal shelf and hardware without mods so the package provides a good value in that you have what you need to get started. But bottom line, (if your installation is similar to mine) you should be fairly proficient with hand tools if your A/C installation is a DIY.THE INSTALLATION: The metal (and sufficiently strong) bracket adapted readily to installing a 6K BTU A/C in a Florida room addition on a 12' wide Park Model. The Frigidaire A/C was designed to fit in a window that slides up and down and was furnished with a support bracket that assumes it will sit on a sill of some type. Since I had no sill this support bracket was discarded. NOTE: This discarded bracket inserted up into the CENTER OF THE A/C to prevent its moving, so see below for the impact of discarding it.USING THE LIGHT DUTY SUPPORT BRACKET: A band saw was used to modify the height of the center support nylon so that the top of the installed support bracket sat flush with the bottom window opening. INSTALLATION INSTRUCTIONS for the bracket also recommended moving the bracket to the heavy side of the A/C; this was done.The two furnished and hardened support screws were more than sufficient to mount the bracket thru the modified nylon into the aluminum window frame. This completed the off-center support for the A/C. Two other plastic support pieces were modified by band saw and mounted (using two of my screws) at the two front corners of the A/C to obtain the same height as the off-center support and prevent the A/C moving left to right. Front to back, the hardware did a good job permitting the slight drop in the back of the A/C. In my installation the very bottom rubber pad rests against the slightly flexible aluminum side wall of the outside Florida room but after several days use of the A/C, the completed 3 hour installation works well. Would do it all again.

Super easy install and secure. Appreciate this.

I purchased this after moving to NYC in what turned out to be a blazing hot summer. I had no previous knowledge of these devices, but not wanting to disregard local laws (and more importantly, get in trouble with our building super) I went ahead and ordered one to keep in full compliance.My first, second, and third attempts to install this were a dud. Pre-war Manhattan apartments, as it turns out, have very thick walls and deep window sill preventing any sort of installation that looks like what is pictured in the instructions. My first two attempts left the unit leaning into our apartment which I knew would mean the condensation would be joining us inside as well. The third attempt achieved the right slope, but left the A/C unit about 1.5 inches above the lip of the window frame (and leaving me with a lot of left open space to block.Finally, I called a local handy man, and he shifted it further down the sill, away from the lip of the window sill that the instructions tell you it should be touching, which allowed the rubber foot on the the brackets support "leg" sit correctly, and the bracket to have the proper slope. $60 later (and after a laugh at my inability to solve the installation puzzle), I now have a properly installed A/C unit that is fully supported, tilts in the right direction, and sits on the sill directly.So, for those living in NYC that need a bracket - this one DOES work, but not as described in the instruction manual.Summary - does its job (+5 stars) but instructions were completely unhelpful (-2 stars)

If you have ever mounted a window AC alone then you know how helpful it would be to rest it on a shelf. If you have ever worried about an AC flopping out if the window was accidentally opened. This bracket provides very good protection against unintended falls. I had no problems mounting it in an "average" double-hung window, but did find it hard to get at the correct angle due to the shape of the AC's underside but I can't see that as any fault of the product - I got it set up very well but it took a little effort to do so. I bought 2 of these (one in this version and one in the heavy duty) for 2 different sized AC's and found both to be acceptable so I disagree with other reviews who rated this as "flimsy" when used with my ~40 pd. unit.

The nut supplied to connect the two pieces of the support bracket is a locking Nylon-incorporating one, so if you're trying to find the right hole to use to get the right angle, you have to be right the first time. No amount of strength will loosen the nut if you are wrong. We even tried melting off the nylon ring with a blowtorch and turning it while heated to over 500 degrees and it's still stuck. We're going to take an angle grinder to the nut to get it off and then replace it and the bolt with ones from the hardware store so this hunk of metal is no longer a useless piece of junk.Get it right the first time, or waste your money. Terrible design.Edit: We just had to order a whole new one. I would have chosen to avoid this product this time around if it wasn't for our apartment complex specifically telling us to get this one, so $26 down the toilet.

And then we found that we didn't need it afterall.
