Thank you for viewing. I purchased the main unit and extension panels in March 2020, but I am selling them because they are no longer needed due to a move. There are some minor scratches and slight yellowing, but they are still usable. Also, one of the handles of the top lock broke, so I repaired it with instant glue and continued to use it. (See photo 2) The instruction manual is also included. Please refrain from purchasing if you are concerned about home storage. - Type: Pet door - Color: White - Lock function: Yes - Condition: Some scratches
