The mountain range is bounded in the north by the Saggau valley, in the south by the Drava or (called the Drau in Austria) and in the west by the Radl Pass (Slovene: ), whilst in the east it transitions seamlessly near Spielfeld and Leutschach into the Slovene Hills (German: Windische Bühel, Slovene: ). In the west the Poßruck is also called the Radlkamm.
