The larger 48 x 48" size requires a van or grip truck for traveling, whereas shaving 8" on all sides makes it more manageable in tight spaces and allows it to fit in nearly all "wagons" or SUVs. Hence the birth of the 40 x 40" Floppy Top Hinge

Simply undo the touch fasteners at the corners, and the Top Hinge Floppy "flops" opens to become a large 40 x 80" black flag that creates a sort of open-sided tent to shade talent, the camera, etc. The frame is hollow steel tubing to cut down on weight, while the solid steel mounting rod can stand up to years of heavy use.
