Three fir wood panels open to 63-in wide and stand 30-in tall, forming a freestanding pet fence that blocks a doorway, a corner or an open stairwell without hardware in the wall. The panels rotate against each other, so the fence bends into a straight line, an L or a semicircle depending on the gap being closed. Solid fir keeps the frame rigid while total weight stays at 3.5 lbs, light enough to carry one handed. It arrives fully assembled and folds to 21-in by 1.6-in for storage behind a door or under a sofa. Small dogs, medium breeds, puppies and cats all stay on the right side of it.
