Configurable into round, square, rectangular, or irregular shapes, this 16-panel metal dog playpen gives pets a secure enclosure indoors or outdoors. A locking mechanism with a convenient door controls access, and thickened metal panels with rust-resistant paint stand up to daily use. Anti-slip footpads and sturdy metal stakes keep the pen stable on different surfaces, and a three-step tool-free assembly makes setup fast. The 24-inch panels suit a range of pets and yard layouts.
