Built with thickened PVC and a full-length magnetic strip, it closes quickly and stays sealed—cutting down on cold air, wind, and energy waste.

Keep your home sealed, comfortable, and pet-friendly

This replacement flap uses a magnetic strip along the bottom that snaps back into place after every use. As your pet passes through, it opens easily, then quickly reseals to keep outside air where it belongs. The result is a more stable indoor temperature and less energy loss throughout the day.

The thickened PVC material stands up to frequent use, including scratching from active pets. It stays flexible while maintaining its shape, so your door continues to function reliably without constant replacements.

Installation is simple and straightforward. With just a few steps, you can swap out your old flap and restore your door’s performance without tools or complicated setup.
