This versatile pet pen has six 36"-wide panels that can be assembled in numerous configurations to keep pets contained, even in hard-to-enclose spaces. For both outdoor and indoor use, the sturdy, galvanized-steel pen makes an ideal dog run, playpen, or portable fence. The panels can be arranged into a 6' x 2' rectangle, 4' x 4' square, or 5' diameter hexagon, or joined side-by-side to form an 18' fence; multiple sets may be combined to create larger enclosures. A built-in gate allows easy access to your pet. Two sets of removable corner pins enable quick assembly without tools. Long pins stake into the ground, short pins allow set up on hard surfaces. The panels lie flat when disassembled for easy storage. Each panel: 38" H x 36" W x 1/2" D. (66 lbs.)
