ABSTRACT:
An elevator cab having a drop ceiling which includes a frame and hanger straps for supporting drop ceiling panels. The hanger straps have first ends pivotally attached to the frame, and they pivot from a low profile shipping position to an extended operating position. The second ends of the hanger straps, when in their operative positions, extend through first openings in the cab ceiling or canopy, with the second ends having tab portions which are bent to secure the second ends of the hanger strap to the canopy. The tabs are bent by an installer from a position inside the elevator cab by use of a tool which is disposed through second openings in the canopy.
