Abstract
A concealed suspension ceiling system advantageously uses a `T` bar grid network used for lay-in ceiling panels. Butterfly clips are secured to upper beads of the `T` bar grid network allowing torsioning springs to releasably maintain the panels suspended beneath the grid. The system can be used for entirely new installations or used in a retrofit application.
