Panels comprising a mechanical locking device and an assembled product comprising the panels

A set of panels comprising a first panel with a first main plane and a second panel with a second main plane, wherein the first and the second panel comprises a mechanical locking device which is configured for locking a first edge of the first panel to a second edge of the second panel at a junction plane such that a first outer corner of the first panel and a second outer corner of the second panel contact one another when the first edge and the second edge are locked at the junction plane, wherein the first main plane is essentially perpendicular to the second main plane and the junction plane is extending between the first main plane and the second main plane, wherein the mechanical locking device comprises:

• at the first edge, an edge tongue which extends from the junction plane;
• and
• at the second edge, an edge groove at the junction plane,
• wherein the edge tongue is configured to cooperate with the edge groove for locking together the first and the second edges in a first direction which is perpendicular to the first main plane, wherein
• the mechanical locking device comprises a dowel at the first edge and a dowel groove at the second edge,
• the dowel is configured to cooperate with the dowel groove,
• a first centerline of the dowel is positioned at a first distance in the first direction from the first outer corner of the first panel when the first edge and the second edge are locked at the junction plane,
• a second centerline of the dowel groove is positioned at a second distance in the first direction from the second outer corner of the second panel when the first edge and the second edge are locked at the junction plane, and
• the second distance is greater than the first distance.
