Will this fit my casement or crank-out window?

Yes. It is designed for casement, crank-out, push-out, skylight and other non-sliding windows. Please measure your window before ordering.

How do I choose between the 300CM and 400CM size?

Measure the total perimeter of your window frame. Choose 300CM for up to 118", and 400CM for up to 157". Pick the closest larger size.

Do I need tools or drilling to install it?

No tools or drilling required. Clean the frame, apply the hook tape, attach the seal, place the hose through the zipper, and close it around the hose.

Does it help keep hot air from coming back inside?

Yes. It helps seal the open window area around the exhaust hose, reducing hot air backflow and supporting more efficient summer cooling.
