The pen sets up quickly and easily (no tools required). Its eight metal panels come pre-connected with welded metal hinges to create one long piece that unfolds accordion-style. Arrange the pen into the shape of a circle, square, rectangle, or other shape, and then clip the two end panels together using the four metal thumb clips (included).
The panels can also be used to corner off a section of the room or to keep pets away from off-limit areas. Or, connect the pen to a metal wire crate (not included) to create a wonderful combination of cozy resting space and room to roam.
