Size: Max 61" Window Kit with 3 Adapters - 5.9"...
"Absolutely impressed with the VIVOSUN Window Duct Kit! Installation was a breeze, thanks to the adjustable design that seamlessly fit my sliding window. The 5.9" diameter, 59" length hose provided a snug and secure connection to my portable AC unit, ensuring efficient cooling throughout the room. I particularly appreciated its compatibility with both 4" and 6" ducting, offering versatility for various setups. This kit is a game-changer for anyone in need of a reliable solution to venting their AC, dryer, or duct fans. Five stars without a doubt!"

Size: Max 61" Window Kit with 3 Adapters - No Hose
Perfect vent insert. It’s easily adjustable and fits different sized hoses. I needed a window vent for my multiple lasers and this was perfect. The hoses on my lasers actually have all 3 sizes this fits, so I just clamped the adapters to the respective hoses and can quickly swap them out into the main panel. The quick and easy size adjustment allows me to move between the different windows very easily with the turn of a screw. If I had to come up with something negative, I’d say it could be a bit wider. The 8” adapter is close to being edge to edge and makes it difficult to get a snug fit into the window frame edges. I just slip a piece of foam insulation in first to give it more space and better seal, so not a huge problem at all. I’m not going to take away just for that, but if by chance the manufacturer reads this… make it just a bit wider so there’s more relief on the sides and it’ll be perfect.

Size: Max 61" Window Kit with 3 Adapters - No Hose
This window duct kit is made very sturdy but it didnt come with any of the thick foam insulation strips to put in between it and the window frame to give it a good air tight seal so thats why i gave 4 stars instead of 5. When i added some of those to either side it made a good seal. For the price it really should include the foam but its made much better than the cheaper brands. Id recommend it but if you have a sliding window id recommend getting the foam insulation strips with it.

Has to be cut to fit 24 inch windows because of the position of the hole on the outside of the one panel, when you add the second piece to allow it to fit the window the second piece partially covers the opening.

Size: Max 61" Window Kit with 3 Adapters - No Hose
This would've been better if it came with a clamp for the hose instead of having to purchase one separately. I would've much rather had that than a third extender piece. Also, while they do include a lot of extenders, they ended up being way too long to fit properly, or just a hair too short without any of them. If the hole had been in the center or on a smaller piece, I could've fit a second extender and made it much more secure but that wasn't the case. Something that bothers me about this set, is that there isn't any way to lock the pieces in place once you have them where you want them. Pretty much anyone could walk up to your window, slide the pieces together, then easily pull it out of the window, and break into your house. I had to add a bunch of extra wood screws to try and stop the pieces from sliding, but that looks bad, wouldn't stop someone if they were determined enough, put unnecessary holes in my window frame, and still leaves me feeling a little paranoid at night. Overall, the quality felt more like something you'd buy from Dollar General or Big Lots and not anywhere close to where it should've been for almost forty bucks after tax. Like, this is barely sturdier than laundry basket plastic. I have ten dollar storage totes that are more rigid. Again, adding in a second extender would've helped, but it's not possible with the hole placement on the main piece.

Size: Max 61" Window Kit with 3 Adapters - No Hose
I build plastic model kits and use an airbrush to do much of the painting, which I do using a desktop paint booth which has a fan to expel the spray from the painting out of a window. The booth did not come with anything else to dispel the paint spray out a window, so I bought this and it works perfectly. It doesn't come with the vent hose, however, but I purchased that separately from Amazon which together with the vent kit, my paint spray booth is now working perfectly to save me from breathing in the paint spray.
