YoleShy Portable Air Conditioner Window Kit with Coupler Adjustable Window Seal for AC Unit, Sliding AC Vent Kit for Exhaust Hose, Fit for 5 inches Ducting, Using Length 17 inches-60 inches

Everything else was fine & easy to install into window.. but it did NOT come with weather stripping.

Not really universal. i have a Toshiba portable unit that I wanted another connection for. Cant find one online, sadly this did not work.

Easy to install.

was able to replace the poorly designed kit that came with my portable AC

This is a well designed, easy to assemble sliding window adapter for my portable A/C.

I got a used window AC unit with a missing piece for the window installation. I read the reviews which seemed like a mixed bag with a few people saying the planks were flimsy. I would disagree. They are fine for their intended purpose. I live in a brick apartment budding that is 100 years old so the window frames had been redone and repainted a million times so nothing really fits perfect but these frames or planks or whatever they are called fit quite snugly.

It worked

It fits my window perfectly

Easy to install and would be 5 stars but its not very fitting with one of my windows. I had to switch rooms for the AC and the living room window is shorter so I had to improvise. It still worked out but it would have been nice if it just fit.

Worked as expected and zero issues
