1. Building panels comprising a locking device, the locking device comprising:
a protrusion and a groove configured to cooperate for vertical locking of a first edge portion of a first building panel to an adjacent second edge portion of a second building panel;
an insertion groove provided in said first edge portion in which a separate tongue is arranged; and
a recess provided in a strip of the second edge portion extending horizontally beyond an upper portion of the second edge portion,
the recess and the separate tongue being configured to cooperate for horizontal locking of the first and the second edge portions,
the first and second edge portions being configured to be assembled to each other by a relative essentially horizontal displacement of the first and second building panels against each other, and/or by angling of the first and second building panels relative to each other,
said insertion groove being provided vertically below at least one horizontal plane extending along a vertical locking surface provided in a third edge portion of the first building panel, said vertical locking surface being configured to vertically lock the third edge portion to an adjacent fourth edge portion of a third building panel,
wherein an entirety of the protrusion is below and spaced from the at least one horizontal plane by a distance, and
said third edge portion being configured to be assembled to said fourth edge portion by angling of the first and third building panels relative to each other and/or by a relative essentially horizontal displacement of the first and third building panels against each other.
