This was purchased over 10 years ago. While current models have sliding doors, this one has a hinged door. I believe the overall size is similar, so I will provide the information listed on Richell's website. Product Name/Wooden Sliding Pet Circle Wide For extra-small to medium-sized dogs Weight guideline/Under 20kg Size/ Outer dimensions: 90-154 x 79 x 70.5H (cm) With tray set: 94-158 x 81.5 x 71H (cm) Inner dimensions: 86-150 x 68.5 (cm) Door opening: 27 x 57 (cm) Side opening: 70.5 x 27.5 (cm) Adjustable width: 90-154 (cm) (11 levels) This is a used item. One of the two trays has a crack on the edge (images 8 and 9). There are some stains, scratches, and age-related deterioration, but no major damage that would impede use. This is a used item based on amateur judgment, so please only purchase if you understand this. It will be shipped disassembled.
