Accessible ceiling grid system

A grid system for torsion spring mounting of aluminum-framed panels is provided which includes a plurality of main grid beams and spacer bars. The main grid beams support a side load mounting clip formed with a slot in the side of the side load mounting clip to engage a torsion spring held by a spring retainer clip such that the panel is supported by the torsion spring. Disengagement of the torsion springs lowers the panels and permits access to the ceiling grid system above the panel members. In a preferred embodiment, the panel has a multifaceted profile including an edge surface that abuts a corresponding edge surface on an adjacent panel. The peripheral edges of the adjacent panel members diverge above the abutting edge surfaces to accommodate either the alignment fin or the tab of the tile stop and diverge below the abutting edge surfaces to form a reveal.
