Five connected steel panels create a versatile metal fence that works as a wide fireplace barrier, baby gate, pet gate, or portable playpen. Each 29-in x 24-in steel panel links with the next so you can angle the frame into different shapes to fit doorways, hallways, or around grills. A walk-through door with a safety lock lets adults pass through while helping keep children and pets contained, and it closes automatically when opened less than 90 degrees. The foldable, 23-lb frame can be wall mounted or set to stand on its own and moved as needed.
