A module having a flat top construction with a planar deck extending to opposed link ends provided with pivot rod openings. The pivot rod openings are oval- shaped with the longitudinal axis of the oval aligned at a 45.degree. angle with respect to and toward the planar surface of the deck. The link ends have a proximal, planar upper surface portion extending from the deck and forming into a distal, curved upper surface portion beginning at a position almost vertically aligned with the outer longitudinal extent of the oval pivot rod openings. The distal portion of the link ends has an inwardly angled, planar outer surface extending downwardly from the curved upper surface portion to a position substantially horizontally coplanar with a lower extent of the pivot rod openings and then to an inwardly curved surface leading to a planar bottom of the link ends. The inner portion of the link ends curves upwardly to a planar bottom surface of the deck. The deck has a concave surface between link ends which serves to receive a link end of a succeeding connected module.
