A fence panel, a method of erecting the same, and a corresponding fence panel kit having a plurality of pickets and a plurality of multi-element rails. The rails include anchor strips that are pivotally pre-attached to the plurality of pickets, resulting in a subassembly that can be folded to an initial compact, folded configuration of the pickets and anchor strips. The subassembly can be unfolded, allowing elongate picket positioning strips to be mounted onto the pickets and the anchor strips. Locking strips are then mounted onto the anchor strips, securing the picket positioning strips in place and completing the assembly of the multi-element rail.
