The panel of the panel system is movable. The panel is intended to be positioned and connected between an essentially parallel lower guide and upper guide of the panel system in order to move the panel on the lower guide. The panel, for example, its lath, comprises at least one claw configured to grip the lower guide. The claw is connected to the panel in such a way that the claw is able to move in the vertical direction when the panel is vertical. When pulled away from the panel, the claw may be attached to the lower guide. The claw tends to retract by itself towards the panel, away from the lower guide. The lower guide may comprise a rail to which the claw is attached and on which the panel may rest as it moves along the lower guide. As an extension of the rail may be an auxiliary rail, comprising, for example, a guide surface.
