Good evening, today the Tüv unfortunately had no plaque for me… All right, except for both thresholdrs. We agreed that it only needed a new “outer sheet” and that this should be incorporated at best in point welded. Is okay for me. The sheets offered on the internet vary between 30 – 130 euros and more. I tend to be a solid and also somewhat more expensive variant, but am not sure what I buy there…? There are “full threshold” repair plates like this one. My questions are: 1. What are the differences between a full swinger and a repair sheet? 2. Is a full sleeper different in the installation / welding process? What is different? 3. How would you do it? Thanks and LG Töfli
