Engineered as a 67.5 in tall dog gate and pet barrier, this galvanized metal pet gate stops larger jumpers from escaping while two width extensions adapt to openings between 30.5 and 41 in. Ultra-dense 1.37 in pipe spacing plus extra reinforcing bars close potential gap zones, and a 21.5 x 65 in main door with a two-sided safety lock lets household members walk through. A lockable 8 x 8 in cat door at the base works as a pet gate with cat door, letting smaller pets pass while taller animals remain contained.
