• ❄Fits Casement, Crank & Skylight Windows：Designed for casement, crank-out, push-out and skylight windows, this portable AC window seal kit fits window perimeters up to 300CM/118". A practical solution for homes and apartments where standard sliding window kits do not fit. • ❄Works with Single & Dual Hose Portable AC Units：The adjustable zipper opening wraps around one or two exhaust hoses, making it easier to vent different portable air conditioner setups.

It supports more efficient cooling and helps keep your room more comfortable in summer. • ❄No-Drill Installation for Renters：No tools or drilling needed. Apply the adhesive hook tape to a clean, dry window frame, attach the seal, place the hose through the zipper opening, and tighten around it. Great for renters and seasonal use. • ❄Water-Resistant Fabric for Summer Use：Made with durable water-resistant fabric for everyday summer use. The flexible design helps create a neater setup than cardboard or tape DIY solutions and is easy to remove and store when the season ends.
