A rackable panel for a barrier is disclosed. The panel includes a rail having a top wall and first and second walls extending downward from the top wall, forming a channel. The panel further includes one or more upright members, and one or more coupling systems for indirectly coupling the upright members to the rail. Each coupling system comprises a bracket having a bridge, the bracket structured to be secured to an inner surface a rail side wall; and a coupling hook structured to receive the bridge within a channel and be secured to an upright member. The bridge is rotatable within the channel, such that the rail can be racked at a positive or negative slope when a force is applied to the rail, while the upright members stay substantially vertical, enabling the panel to be used on a wide variety of terrains.
