ABSTRACT:
An interconnected runner system formed by elements structurally interconnected to form main runners and intersecting cross T runners. The main runners and cross T runners are structurally interconnected to prevent unintentional or accidental disengagement, and function to provide a structure wherein objects may be suspended beneath the suspended ceiling supported from the grid forming runners throughout the grid structure.
