With the MidWest Universal Pet Playpen Extension Kit, you can expand your pet's existing play space without purchasing a brand-new pen. This handy kit comes with two, 2-foot panels that were designed to fit most standard playpens and exercise pens. Once connected, they can expand your space by four feet. That's four additional feet your furball can stretch out and play—still safe within the confines of their play space! It's easy to install using four thumb-snaps—and no tools—plus, it's made with a protective e-coat for a long-lasting shine. Made in several sizes to fit a variety of exercise pens, this extension kit makes it easy and affordable to give your pal the extra space he deserves.
