Automatic closing pet door with magnets, easy to install. - Model: PD-01 - Size: W220 x H240 mm - Features: Automatic closing with magnets - Installation: Easy installation Thank you for viewing. This is a pet door for dogs and cats that attaches to a screen door. It closes naturally with magnets. I tried installing it once, but it seems the pet couldn't recognize the door, so I only used it for a week. I lost the screws when removing it, so please prepare 4 tapping screws B-O type. I will sell it at a reduced price accordingly. There are fine scratches because it is plastic. Please check the images.
