Sized to fit openings from 28 to 43 inches wide, this 30-inch-tall baby gate is built for stairs, doorways, and hallways where a secure, no-bottom-bar design matters. Removing the bottom bar cuts down on tripping and lets the gate swing fully open for an unobstructed walk-through, which is handy at the top of stairs. The steel and ABS plastic frame keeps bars spaced 2.1 inches apart, narrow enough to block little hands and paws, and a dual-lock system on the reinforced side bars keeps children and pets from working the gate open on their own. Installation is drill-mounted, with the full hardware kit included; just line up the upper and lower mounting holes on the same vertical plane for a stable, wall-anchored fit. Once mounted, the gate opens and closes with one hand, so you can get through while holding a child or carrying items. The black finish and rounded, anti-scratch edges make it easy to live with in a kitchen, hallway, or stairway doorway every day.
