Safe and thoughtful design: Made of ABS material, weatherresistant with a smooth and durable surface. The transparent flap lets your pet see through the door. An exterior rain seal helps keep water out, and a brush strip reduces noise when the door closes. Fourway access with simple control: Can be adjusted to four modes: out only, in only, both in and out, and fully locked using the red and green switches with tabs. Easy control of your pet's in and out movements. Encourages exercise and independence: Lets cats and dogs go in or out without your help, making potty breaks or play time more convenient and reducing interruptions. Easy to install: Comes with detailed installation steps for quick setup. Includes 8 screws and caps, and can be installed in doors, cupboards, panels, walls, and similar surfaces. Use scenario: A dog can access an outdoor potty area by setting to out only during the day, while the door remains closed otherwise. Use scenario: A cat can visit a separate play area or litter zone by switching modes to in only or out only as needed, keeping other rooms secure at night. Use scenario: In homes with multiple interior doors, install this pet door to allow movement between rooms while still providing the option to fully lock it when desired.
