Rackable panel assembly and methods of assembly thereof

A rackable panel assembly comprising:

• a plurality of vertical members each having a pair of opposed ends and at least one sidewall extending longitudinally therebetween and having a rail engagement opening defined therein;
• at least one rail having a pair of opposed ends and at least one sidewall extending longitudinally therebetween, said at least one sidewall defining openings spaced along a longitudinal length of the at least one rail, each of said openings adapted to receive a vertical member of said plurality of vertical members therethrough and at least partially overlap or cover the rail engagement opening of said vertical member;
• and
• at least one coupling member adapted to be at least partially received in each said vertical member for pivotally coupling the vertical member to the at least one rail, said coupling member having at least one protrusion and a biasing member for biasing the at least one protrusion outwardly from the rail engagement opening in a direction perpendicular to the length of the at least one rail to pivotally couple the vertical member to the at least one rail, wherein each said opening is elongate so that said vertical member received therethrough is pivotable relative to the at least one rail.
