[Rail Design and Good Sealing]Do you still hate hot air entering your room in summer? Plug this AC window kit into your window track and keep your room cool. Unlike other AC vent panels that require additional self-adhesive tape to seal the space between the window and panel kit, our Portable AC Vent Kit has been modified to fit snugly against the window, preventing heat transfer back and effectively reducing power consumption.[Universal AC Vent Kit]This portable air conditioner car window kit includes 4 adjustable sliding plates (16.9x3.9 inches), 1 coupler with a diameter of 5.1 inches (about 13 cm) and 5 screw fittings. Fits all 5.1inch diameter air conditioner exhaust hoses (counterclockwise AC exhaust hose). Compatible with most portable air conditioners on the market. (without hose)[High Quality Material]Innovated based on the existing products in the market, our air conditioner window kits are made of high quality thickened PVC, which is resistant to high temperature, extrusion, aging, and easy to store in winter, and can be used year after year. The mesh coupler prevents small animals or litter from entering the extendable AC vent kit hose to damage your AC components.[Vertical and Horizontal Use]Portable AC window seals fit most vertical and horizontal sliding windows/doors. The plate combination is adjustable in length (16.9-62 inches, about 42.9-156.2 cm), use 2 plates, 3 plates or a 4 plate combination depending on your window size. After installing our sliding AC ventilation kit, your windows can still open and close freely without any problems.
