Expandable from 34.5 to 154 inches, this six-panel pet safety gate uses 270-degree rotating hinges to form straight barriers or enclosed pens across doorways, stairs, and fireplaces. A secure double-lock system holds the door open at 90 degrees and closes it automatically, while a robust metal frame with ten extension tubes and mounting hardware keeps the fence sturdy. The foldable panels store flat when not in use, making the gate a flexible barrier for homes with dogs or other pets.
