Ten HDPE panels connect with 360° rotating joints to form a dog playpen that helps contain your pet while leaving room to rest or play. Each 21 x 31.5 in panel lets you create straight sections or angled corners to fit indoor rooms, RV campsites, or yard spaces. A built-in door with a 14.5 x 30.5 in opening and double latches allows you to step in and out while helping prevent pets from pushing it open. Suction cup feet and ground stakes enhance stability on smooth floors or soft ground.
