The Ikonart Extender Bar is specifically designed to be used with the Ikonart Starter-Kit, to raise the light up higher when exposing the larger 12"x18" Ikonart Textile Film and the 12"x18" Ikonart Stencil Film.
This Extender Bar is compatible with the original acrylic Ikonart Exposure Stand or the new metal Ikonart Exposure Stand. Just remove the original shorter bar and replace with this Extender Bar in order to raise the light. You will need to flip the light around so it is not over the base when exposing the large film sheets.
