We have 5 or door in our house, stair gate. Since we purchased this gradually and there are different steps as well as requirements, we have a total of 3 manufacturers in the home. This grid of Lindam we have for the stairs between the upstairs and downstairs. We opted for the elegant look of the model. Since we have a modern simple staircase, this was by all child protection grilles the most appropriate model. We also need a wingspan of 100cm. According to the manufacturer's instructions is also possible with this model. Here depends on the basis of its own weight through the grid and looks wrong. The connectors differ. I add times with a few pictures. Here it comes to friction and kwitscht very loud and unpleasant when opening and closing. We would buy the grid not again. We still have a better idea of what looks also very elegant and functionally better by far. This grid is only to use if you do not have more than 60cm to bridge it.
