So you can air out your home without windows or balcony doors slamming shut in a draft: Place the stopper in the bottom corner between the frame and the open sash to hold the sash in place.
- Stepped shape fits the frame – The notch sits on the bottom edge of the frame, and the sash rests against the end. This keeps it open instead of letting it slam shut in a draft.
- No drilling – Simply insert it and remove it whenever you like. It leaves no marks on the frame, making it ideal for rental homes, too.
- Plastic honeycomb structure – The open honeycomb cells make the stopper easy to handle. Take it from your bedroom window to your balcony door in seconds.
- 4 colors – White, black, red, or blue-gray to match your window frame.
- Check the fit – Designed for inward-opening sashes with a stepped bottom frame like the ones shown in the photos. Check your frame profile before ordering.
For balcony doors, patio doors, and windows on warm days when you want to air out your home for longer.
