Factum under cabinet IKEA, looking for an additional drawer set

Hello,

I am trying to equip a Faktum base cabinet with 5 drawers. At the bottom one with an 18 cm panel, the other 4 panels just under 13 cm. The problem is that only the first two drawers from the bottom can be installed. The spacing for the third one is not correct. You can only compensate for this by rotating the panel. But then the same problem occurs with the next drawer. I am considering adding a row of additional holes because the spacing of the existing hole pattern does not fit. But there is little space and it has to be quite precise. The holes should not go too deep either, as one side is openly visible.
Is there perhaps an extra drawer set for this cabinet? It is quite strange that the back edge of the drawer is almost the same height as the front panel.
Does anyone have experience with this? I would be very grateful for help!

Regards
Jens

Check everything once again. Note that for the lower rail a different hole is used than for the other four. For the flat drawers, the front must be attached in such a way that the bracket is closer to the upper edge.

If you have purchased drawers (used) without assembly instructions, it should be noted that there are two versions that are assembled differently.

Hi,

please be sure to follow the assembly instructions, it definitely fits! Unless a hole is already incorrectly drilled from the start. Unfortunately, that can happen, although rarely.

Otherwise, the Ikea expert has already said everything.

Good luck!
