ᐅ Ikea METOD kitchen hanging rail 60205664 for base cabinets?

Hello,
what has been your experience with the suspension rail 60205664 for base cabinets?
What is it used for: installation or as a load-bearing element (in addition to the 4 legs of the cabinet)?

If it is indeed necessary, can a lower load be assumed as long as the legs rest on the floor, so for the dowel design a load of 0.26 kN (26 kg / dowel)?

Hello, originally the mounting rail was supposed to replace the rear legs. However, for our kitchen, we still installed the legs at the back. The rail then serves only two purposes:
1. Easier alignment of the base cabinets.
2. Tilt protection, since our base cabinets contain only drawers and pull-outs.

Best regards
