For use on friction fed cutters. Can be used safely on pretreated or pre painted wood, urethane foam board, glass, tile, and acrylic. Rubber is trimmed back ½” along each edge so the wheels can clap down on the 5-mil polyester film liner and carry the stencil through the computer. Since this type of plotter has no sprockets, holes are unnecessary (as in other computer stencils). Available sizes 19-7/8" and 24" in 10-yard rolls.
