Convenience AND Safety. Dont be fooled. Not all auto-close baby gates are created equal. The Qdos Auto-Close SafeGate meets the toughest European Safety Standards as well as the US and Canadian Standards. Just release the opened door and it automatically closes and latches into a locked positon behind you. For added peace of mind, Qdos added the At-A-Glance Indicator so you can confirm with a quick glance that the gate is securely locked. If a baby gate is not installed properly, itҒs not safe. Qdos makes it easy to make sure your gate is installed properly and securely the first time. QRF Spindles make installation over quarter round moldings a breeze, and the included magnetic level and AccuInstall Indicators simplify the process. SecureHold֙ Adhesive wall cups secure the gate and protect your walls. Gate height is 29.9", expands to fit openings 29.3" - 36.8" with two included extensions, additional extensions available to fit openings up to 47.8".
