400CM (157") Portable AC Window Vent Kit with 2 Zipper Doors, Universal Casement Window Vent Seal Kit for Mobile Air Conditioner and Dryer, Upgraded Full Sealing Waterproof AC Window Seal Kit

This kit did exactly what I needed it to—and at a great price. Other solutions like custom plexiglass were going to cost hundreds when I checked, and even a DIY approach would’ve been at least three times the price of this. I had it installed and my portable AC exhausting out a casement window in under 15 minutes. The zippers and seal feel secure, and it’s held up well so far. If you’ve got casement windows and need an AC venting solution, I highly recommend this kit. It’s simple, effective, and way more affordable than the alternatives.

This allowed me to use my AC but it looks awful and will need to redo the Velcro strips every summer so I can close the window in the winter.

Very good

Great idea and well constructed, BUT! Does not work with old style casement windows which have a gap on the hinge side of the window when open..

Works as described.

Simple and works great to keep bugs out while drying clothes.

More trouble than it's worth. Flimsy and very difficult to install.

Nice quality and I made it work but it is much longer than needed and not wide enough for the average window

Lo sue para una puerta regular y me sirvió super bien. Muy buen material.

La verdad bastante bueno ayuda muy bien aislar la ventana cuando se requiere ya que no necesitas nada más es muy importante que midas el tamaño de tu ventana para evitarte complicaciones en la instalación. Lo recomiendo muy bien. Cuando coloque el no voy a aire acondicionado portátil compraré otro
