Review: Fast delivery - Don’t fit but it’s ok
Review: Very tight fit - Perfect replacement for my LG unit. I had to press around the outside to get this bracket to fit inside the exhaust of the air conditioner but this gave it a nice tight fit. It seemed to only turn part way to lock but this is plenty enough to keep it in place. Being a universal replacement part, I realize it’s difficult to make a 1 size fits all. The name brand replacement’s price is insane for my LG. This product is very affordable while keeping the quality top notch.

### ⭐ Did not fit Black & Decker
*by S***R on November 23, 2024*

I have the Black & Decker model BPACT14H portable AC unit. The exhaust opening is exactly 5.9 in, but this coupler I purchased did not fit. It was too big no matter how I tried to force it in. The good news is that the seller gave me a refund and I did not even have to return the piece. I would recommend that the seller list the specific models that this coupler fits, so that I would not have wasted my time purchasing the wrong item. It is definitely not universal for any portable AC unit with 5.9" exhaust opening. I know everybody always says this, but I wish I would have read the one star reviews and that would have tipped me off.
