Factum IKEA kitchen, looking for instructions on how to attach moldings

Hello everyone!
I have already searched through the forum but can't find any real help. That's why I'm reaching out to you in the hope that you can give me good tips and/or maybe even a tutorial (with or without pictures)! Next Thursday we are getting our new Faktum kitchen delivered! Hooray! What we don't really know, however, is how to attach the side trim strips? At Ikea, they didn't really tell us anything about that...

I would be really grateful for any tip and/or photo!
Best regards, Bine

Which fitting strips??? Where are they located and what is their purpose?

Hello,
a filler strip or filler panel closes the gap between a cabinet and, for example, the wall.

At Ikea, you cut it from a baseboard or a cover panel. There are no special fasteners for it. You either use two metal brackets or two pieces of wood with a rectangular cross-section.
I usually do it like this: screw the piece of wood flush with the edge facing the cabinet to the filler strip. Insert the filler strip, (hold it carefully) and drill through a hole from the inside of the carcass with a 2-3 mm drill through the carcass wall and the piece of wood at the appropriate spot. Then put in a chipboard screw and it's done.
Of course, you can also attach the filler strip before you fully assemble the cabinets. Then the filler strip can be screwed on more easily from the outside. Since it can be fiddly to adjust the strip to the unevenness of a wall, I have so far preferred to mount the filler strips later so that I could use my kitchen as quickly as possible.

Hello IKEA expert!
Thank you very much for the detailed description and the good tips! Then we will try to get it done like that on Thursday! Thanks again and have a nice rest of the weekend!
