This is some more information that I don’t know where it will be seen.
The Picture Frame Backdrop is a variable size, rigid backdrop well suited for front and back lighting and projection effects. Constructed from 1/4″ thick Sintra® PVC Foam board and weighing under 3 lbs each, the square Frame has a 2′ x 2′ outside dimension. The inside square of each Frame measures 15 5/8″ x 15 5/8″ and is covered by a translucent, stretched cloth.
To achieve the desired size for the event, Frames are assembled along a grid formation and joined together with quick release latches that lock out of site on the backside.
