This metal safety gate is particularly useful as it closes automatically from both sides thanks to its magnetic lock. The gate for doors and stairs can be used for openings between 75 - 80 cm. If you wish to childproof a larger opening, you can buy the separately available 9 cm and 21 cm extension, as well as the Y-Spindle for round stair railings. One extension + Y spindle can be used on each side of the gate, making a maximum of two extensions possible. , , The gate's assembly is very easy. It is fixated in between doors or stairs with four fixing screws that work with pressure. They simply need to be twisted until the closing mechanism engages. By using this installation system, no drilling is necessary and annoying holes in your wall are avoided. The gate's door can be opened by adults with one hand only leaving the other one free for your child. When letting go of the door, this bounces back and closes automatically. , , For safety, the green/red indicators on the lock show whether the door has closed correctly. Thanks to its double closure mechanism with pulling and lifting, babies and toddlers cannot open the door. By using the separately available extensions of 9 cm and/or 21 cm, you can use the Autoclose N Stop 2 for openings up to 122. , , The following measurements and combinations are possible: 75 - 80 cm = safety gate only84 - 89 cm = safety gate + separate 9 cm extension93 - 98 cm = safety gate + separate 9 cm extension + separate 9 cm extension96 - 101 cm = safety gate + separate 21 cm extension105 - 110 cm = safety gate + separate 9 cm extension + separate 21 cm extension117 - 122 cm = safety gate + separate 21 cm extension + separate 21 cm extension Please note:This product is a self-adjusting safety gate i.e. tilting of the side part is corrected by tightening the fixing screws in the frame, thus enabling a secure position and parallel fixing of the side parts in the area of the closing mechanism.
