Wide Panel
300C/L C-Grid
Hunter Douglas Wide Panel Ceilings
enables the architect to design aclosed ceiling with high performancealuminium or steel materials. In orderto give maximum freedom in design
there is a wide choice in panels withsoft edges for a monolithic ceiling
appearance or panels with square edges
which results in a smooth ceiling with anarrow butt joint.

between the C-grid sections (2).

6928SUSPENSION
The suspension structure consists ofexposed C-grid sections (2) which areinstalled parallel to each other to form
a continuous main support. These arecross braced by primary angles (3)to ensure the spacing between thesections. A square grid system can bemade by incorporating C-grid crossmembers that are butt joined against
the main section. The cross connector( 9 ) ensures a close fit at the junction
points.
