Transparent plastic panels create a dog playpen that also functions as a pet gate, allowing you to see your pet while limiting their movement. Eight interlocking panels assemble without tools and can be arranged in square, rectangular, or hexagonal layouts to fit different rooms. The locking door with a 17.5 x 21 in opening lets you step in easily while dual safety locks help prevent accidental opening. Thickened HDPE frame sections, suction cups, and included ground stakes help keep the pen stable indoors or outdoors.
