Abstract:
Suspended ceiling grid runners include a flange extending laterally to both sides, the flange forming a three dimensional face including sides visible from below a plane of the grid, opposed cross runners intersecting through runners with their ends joined by mutually interlocking end connectors extending through a slot in the through runner, the cross runner ends including end edges configured to abut a respective side of the flange of the through runner, a connector when connected to an opposite connector causes the associated end edges to resiliently locally deflect the abutted flange side to substantially eliminate any gap therebetween.
