The Bresser BR-D45 Background Support 380x450cm Pro-1 is a solid background system with a background of paper, vinyl or textile. On the 2 metal lamp stands you attach a 5-piece cross bar with which you can define the width of the background system. On the system you hang a background of 180, 270, 360 or 450 centimeters. There is a coating on the stands so that they do not reflect undesirable light. You adjust the height of the system from 120 to 300 centimeters.
