Structure:
The structure is quite simple by hand. As we are connected not only the actual door yet both the left and right need an extension, I had this yet each with a thin metal part to the main part. Then the screws at the outer ends had to be as far in or out screwed that whole structure holds.
Quality / Maintenance
This is where we come to the absolute weakness of the product. Due to the two extension pieces the whole structure is relatively fragile. I had therefore with several cable ties fixed to the wall and between the connectors, so that the construction also stops just rudimentary.
Now, when our little girl tries to shake the railing (which quite often happens), I have the screws tighten again. Especially the connecting pieces do not just lead here to a good stability. The door itself must be gezoge by hand in the leadership unfortunately. Ideally this should be done automatically.
A further drawback is that the structure starts to rust very quickly. We use the grid but in the open, this grid is probably not designed.
Conclusion
The quality of the product in terms of stability and comfort in my opinion is not enough. My goal was to have a stable structure, which I did not have to fix it with cable ties and I do not have to constantly re-adjust further.
