Hung windows do not utilize the same window screen replacement method as hinged windows. See the video under the main product image to see how it works. Vent your portable AC throu gh single and double hung windows without blocking your view or leaving gaps that leak hot air. This custom portable AC hung window vent kit is precision-cut from durable ¼" acrylic and sized to your exact window opening, creating a proper seal that actually keeps hot air outside. Each insert eliminates the portable AC hose window gap that kills cooling efficiency. The quick-attach snap-fit collar locks securely into the panel, creating a sealed exhaust path so your portable AC vents outside instead of recirculating warm air back into the room. Our hung window AC vent kit is designed for both single and double hung windows and installs using a non-permanent mounting system that sets up in minutes, no drilling required. Standard inserts are available in 12" heights, with taller custom sizes available when needed. Show more
