Thank you for viewing. IRIS OHYAMA System Circle Roof P-STNY-550 White, Width 87 x Depth 57cm Prevents pets from escaping. This is a dedicated roof for the system circle with a tray. By attaching the roof, you can prevent pets from escaping when you are away from home. No screws or tools are required, and it can be easily installed with the included joints. I have opened it, but it is unused. (Only the corner joints are unopened) (The bag has tape repairs) When shipping, I will wrap it in bubble wrap.
