Sixteen metal panels connect to form a dog playpen or barrier that helps contain pets indoors or outdoors while maintaining visibility through the mesh fence. Each 31 x 24-in panel joins with metal stakes so you can create straight runs or enclosed shapes to match your room or yard. A large built-in door measuring 11 x 16-in offers a convenient entry point and secures with a lock. Rust-resistant paint, rounded corners, anti-slip footpads, and sturdy stakes support stable, long-term use on different floor surfaces.
