This baby gate swings across openings anywhere from 29.5 to 46.4 inches wide, so it fits a narrow hallway or a wide doorway without buying a different size. Standing 30 inches tall with a walk-through opening over 21 inches wide, it's roomy enough for a stroller to roll through while still keeping curious toddlers and pets from climbing over. The 180-degree swing stays open at 90 degrees for hands-free passage and swings shut on its own from any lesser angle, and the dual-lock latch needs both a lift and a pull to release. Choose pressure mounting for a no-drill setup finished in about 10 minutes, or switch to the included wall mount hardware for extra holding power at the top of a staircase. Built from powder-coated iron with 2.1 inch bar spacing, the frame resists over 45 pounds of pull force and 33 pounds of impact, standing up to daily tail wags and toddler tests.
