Now that baby is on the move, you can easily keep stairways off limits with the Ready to Install Gate from Safety 1st. This hardware mounted security gate with a no trip design is perfect for any room in the home including the top of stairs, bottom of stairs, and between rooms. There's no measuring, marking or need to level thanks to the innovative packaging. The gate comes out of the box in one piece to ensure your install will be hassle free. While other gates require multiple parts, and extra steps that lead to frustration; this fully assembled gate installs easily in 15 minutes - half the time of a standard gate install. Operating this safety gate is easy too. The no threshold design means no trip hazard at the top of the stairs. One-hand operation and a swing-open door make it easier to pass through, and the gate closes with just a push, letting you get on your way. Note: Requires a flat mounting surface at least 3.5" wide.
