Air Lock for Portable Air Conditioner,Window Seal for Mobile Air Conditioning. Max Size 14x60 Inch

This is a great window seal for some more awkward types of windows. I have a wide window with two upper narrow windows that open. You just simple wipe down the space you want to seal, secure the sticky Velcro and then fit the seal. It’s very simple, yes I have some extra material but it’s very easy to use the Velcro fastening to secure it. The zipper function works perfectly fine to secure your vent between the zippers and then fasten a zip tie for added security.I have read some of the recent reviews and I am quite surprised by them, I am extremely happy with my purchase and I was very impressed with how quickly I received it from USA. This window is the the only window seal product I would recommend!
