Abstract: An interlocking fence system is disclosed. Two spaced-apart upright posts (8, 10) attached to a grade G support an upper rail (4) with an offset locking aperture (26) and an alignment aperture (32) and further support a lower rail (6) with an alignment aperture (40). A picket (2) has a locking slot (22) with an edge (28) of the locking aperture (26) in the upper rail (4) serving as a tab to restrict axial movement when inserted therein. Alignment aperture (32) in the upper rail (4) and alignment aperture (40) in the lower rail (6) serve to restrict lateral movement of the picket (2). To support the rails (4, 6), retaining slots (24, 24?) in the upper rail (4) and retaining slots (42, 42?) in the lower rail (6) can be retained by an edge (38, 50, 38?, 50?) in support apertures (12, 14, 16, 18) in the posts (8A, 10A).
