A/C Safe Universal Light-Duty Window Air Condition

Great idea
Installed it on a second story window unit installation worked well

Sufficiently Flexible
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.

NYC requirement – installs a bit different that the instructions say
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)

Nut Supplied Is A Locking One, Is Not Removable
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.

While there was initial skepticism on whether this will hold the weight of my AC, it did a fantastic job. Installation was easy – just need a drill machine and screwdriver.

I like the many plastic supports that attach to the window sill for many possible heights. This is a little shorter than I thought, but it works well.

It is very strong, good value! As you can see my air conditioner cannot lay flat because it has bumps underneath and when I try to lay flat then I cannot have the correct angle to get a slight slope downward. But happy, it does the job!
