once the ceiling panel 10 is connected to the grid members 12 the ceiling panel 10 will automatically be in alignment to allow for easy closure by pivoting the ceiling panel 10 upward and snapping in the three other flanges 26 28 and 30 fig2 is a cross section of fig1 taken along line 2 u2014 2 looking in the direction of the arrows and shows the grid member 12 and the hinge 24 along the first edge 25 of a first ceiling panel 10 and the flanged edge 26 of a second ceiling panel 10 the grid member 12 is fabricated out of a single piece of die formed sheet metal the grid member 12 after fabrication includes a bulb portion 34 a channel 36 and a double layer bridge portion 38 that connects the bulb portion 34 and the channel 36 the overall shape of the grid member 12 is to give the member 12 strength to prevent flexing typically apertures not shown are placed along the length of the bridge portion 38 so that wire hangers 16 can be threaded through and wrapped around the bulb portion 34 once the wire hanger 16 as shown in fig1 which can be in the form of a wire is threaded through an aperture not shown and around the bulb portion 34 the wire hanger 16 is wrapped around itself.
