This device slips over the door and locks to the door stop molding, preventing children /pets from opening the door past a set distance. I use this device to allow airflow into my bedroom while preventing my cat from entering while I am away.

The original design is great - I just wanted more sizes! I have included the Fusion360 file for even better customization. Create the perfect fit by easily changing key parameters such as door width, door thickness, width of the gap, and more. 

File name convention:

  • “O” for size of the opening created, in mm
  • “T” is for the thickness of the door, in mm
  • E.g. O50T35 creates a 50mm opening and is designed for a door that is 35mm thick    

Disclaimer: I do not guarantee the safety or security of this device. Be aware that children or pets could get stuck in the opening this device creates.
