42-in Tall Folding Metal Dog Exercise Pen - 16 sq ft Play Area

In this review the 42-in tall folding metal exercise pen is judged on durability, ease of setup and suitability for small to medium pets. The bottom line: this pen creates a clear, secure play area that is best for owners who need a sturdy, portable enclosure without a door. Its single strongest point is a simple, tool-free setup and a black e-coat finish that stands up to outdoor use, making it a practical choice for people who move a pen between indoor and outdoor spaces.

Key Features

• 16 sq ft enclosed space: When fully expanded the pen provides a generous 16 square feet of room so a medium dog or several small pets can move, play and rest comfortably.
• 42-in height: Taller-than-average walls help contain more energetic small and medium dogs and reduce the chance of escapes by curious pets.
• Black e-coat finish: The protective coating resists rust and weathering, so the metal pen is suited to regular outdoor use as well as indoor placement.
• Fold-flat portability: Eight panels fold flat for compact storage and travel, making the pen convenient to move between rooms, yards or trips.
• No tools required: Assembly uses four thumb-snaps and eight ground stakes, so the pen sets up quickly and can be secured outdoors without hardware.
• Accessory kit included: Ground anchors and assembly instructions are provided to help ensure a safe, stable installation on a variety of surfaces.

Who It's For

The pen suits owners of puppies, small dogs and other small animals such as rabbits or ducks who need a contained play area that is easy to move and durable outdoors. It is a good fit for people who prefer a no-door layout for continuous perimeter strength and fewer weak points.

Those who need a pen with an integrated door for frequent in-and-out access or owners of very large or highly athletic dogs that can jump or push hard against panels should consider alternate enclosures designed specifically for heavy chewers or very large breeds.
