Good product and good seller

I like the coupling between the two hose sizes. This made mating up the 5.5" hose from the Black + Decker portable AC to the 6" I bought to exhaust to the outside through an attic. The flange has 2 sizes on it, so you have to cut the hole to 6.5 inches and then slip it in the wall and try to center the ring around the larger than 6" hole. The way it's configured I would have to go inside the attic and take the 6" hose out to plug up the hole from that side with the qay the plug is for the larger size hole... hence the 4 stars. Kinda hinky install, but it looks good once it was caulked in. 1st pic is before I caulked it in.

Worked perfect for my stand alone AC unit with the exhaust coming out the house also came with cap when the winter comes I screw cap on seal it off.

Simple and easy to install, looks clean.

The flange should be attached to the 6.5" side of the fitting and then reduce to the 6" side. If it was designed that way, then you could easily attach a 6" duct and the keep the fitting flush with the wall. With the current design there is no way to attach pipe to vent outside and it protrudes 3 inches from the wall.I ended up cutting off the mounting flange with a saw. I cut a hole in the wall tight around the 6.5" end and was able to metal tape a 6" duct outside through the wall. I caulked around the pipe and it worked out well.The air conditioner pipe doesn't thread in all that easy, but it will go with some work. There are not many fittings like this available is the only reason I bought it. It's over priced.

Nice product. Comes with a rubber gasket. I used this vent in a van floor for a portable unit. Works great.

Bought this to match a hole saw, and it was almost right on. The hole saw it recommends is slightly bigger, so you have to be careful of the screws being right on the edge, but otherwise it's perfect.
