This 6 panel heavy duty metal pet playpen is constructed with corrosion resistant coated metal, delivering great performance for indoor rooms, backyard, camping and Rv travel. Each panel is joined by robust hinges to build a stable framework that resists impact from pets daily activities.

Beyond being a pet exercise yard, it can also work as doorway barrier, stair guard, corner fence or indoor room divider to set clear pet activity boundaries. Quick assembly takes only 5 minutes by inserting metal connecting rods. You can arrange it into square, rectangular or other custom shapes to fit various spaces.
