ABSTRACT:
A ring binder holder for transparency sheets comprises an elongated, rectangular ring-engagable strip of sheet material such as plastic or heavy paper having two parallel longitudinal edges. A line of ring-engagable openings in the strip is parallel and adjacent to one of the edges. Along the other edge is a line of adhesive on the strip that is adapted to adhere and attach the strip to an edge of a plastic transparency sheet. An elongated opaque flap is hingedly attached to the strip along a line that extends the entire length of the strip between and parallel to the line of ring-engagable openings and the line of adhesive. The flap is hingedly movable between a closed position covering the adhesive line and an open position covering the ring-engagable openings and the adjacent edge of the strip.
