The stable metal safety gate is suitable for door frames or stair railings with a width of 75 to 80 cm and provides safety for little explorers. It is secured in place with tension screws and can be individually extended up to 122 cm with extensions. The child safety gate is clamped between door frames or walls using tension screws. Since it leaves no drill holes, it is ideal for rental apartments or for use on other doors and stairs, for example, at grandparents' houses. The Open'n Stop safety gate features a manual closing mechanism that reliably locks into a child-safe closure. Thanks to the dual locking system, only adults can operate the safety gate. The Open'n Stop can be opened in both directions with just one hand, keeping the other hand free for your little one. With the variable extensions of 9 cm and/or 21 cm, both narrow and wide passages (up to 122 cm) can be made child-safe. Extensions of 9 cm and 21 cm are available for the Open'n Stop Safety Gate. If you have a stair railing with round bars, the child safety gate can also be secured with separately available Y-spindles in addition to the 9 cm and 21 cm extensions.
