The refrigerator stands firmly on the floor and I have never had a freestanding refrigerator move towards me when opening and closing it. It is a built-in appliance that does not have a "properly closed" housing, otherwise the insulation would not be freely visible. That is why a right side panel is necessary. On the left it is unnecessary, but already installed or at least the countertop cut to fit. For whatever reasons, the countertop could not be extended all the way to the wall, so it also cannot be attached to the wall. Personally, I don’t like this solution either, since dowel holes cannot be drilled with millimeter precision and adjusting the height can then be difficult. If I understand it correctly, the only really remaining problem is that the right panel does not have a plinth recess. This just needs to be cut out accordingly. The plinth panel can then cover the cut edge. However, I would still apply an edge band to the cut edge. There does not need to be a gap between the countertop and the refrigerator, but the refrigerator should not bear the countertop, otherwise the insulation would not be exposed. Everything would be a bit clearer if one could see something here. I implemented a support panel myself by screwing an aluminum U-profile to the countertop, which supports the top side. The top side also sits in an aluminum profile at the bottom and Pax feet are attached to this. The whole thing is height-adjustable. However, this construction is not quite ideal if you have a side view of it.
