Extended and combined with Y-spindles to attach them to stair railings with round spars. The children's grille can be securely clamped between stairways, walls or door frames by means of adjusting screws. It doesn't have to be drilled. To walk through, adults can open the door in both directions with just one hand. Thus the other hand is free for the small treasure or shopping bags. The Stop N Safe 2 has a manual closing mechanism with a double safety catch, which prevents uncontrolled opening by children. With separately available extensions of 9 cm or 21 cm, the door protection grille can be flexibly extended up to a width of 110 cm and thus also used as a stair protection grille. In addition, the combination with Y-spindles on stair railings with round or oval bars is possible. If necessary, the Y-spindles are mounted on one side of the grille instead of the set screws. That's why the same ones come up.
