A set of panels includes first and second panels, and a mechanical locking device for assembly by vertical relative displacement of the panels. A locking strip extends from a first edge of the first panel in a direction parallel to first and second panel surfaces of the first panel. The locking strip includes a locking strip edge, and first and second locking strip surfaces respectively extending in directions substantially corresponding to those of the first and second panel surfaces. The locking strip includes a locking element cooperating with a locking groove at a second edge of the second panel for locking in a direction parallel to the first panel surface. Opposite edges respectively include cooperating tongue and tongue groove for vertical locking. The first and second edges respectively include first and second engaging positioning elements to decrease vertical movement of the panels in the locked position.
