We needed a grid, so that the children can not walk to the kitchen, but the view is not denied to them. However, our kitchen door is narrower than normal doors, so this guard not fit between them. However, the two outer parts fit exactly on the door frame that we had the idea to remove the screw parts. After that, we pierced the door guard and screwed it directly to the wall and door frame. Optimal is that the grid can be opened on either side (can be as well as our other). Because the voltage but is not quite as good by our eigenbau measure (mounting on the wall), the door is not as engaged to, as they should be. Advantage for adults: short lift, and you can open. Disadvantage: Three-year child knows the trick, but hear it, not reinzudürfen when the grid is on. Year-old child has the hang of not out. An alternative for our 60cm passage width we have not found, so the drilling solution.
