This is the original invisible Adhesive Disc Hanger, tested and proven for more than 40 years. The Adhesive Disc Hanger is the answer to ugly plate wires, clips or hooks. The Disc Hanger sticks to the back of the object and holds it flat and secure against the wall. Best of all, it cannot be seen. The Disc gives a permanent adhesion of great strength to a glazed or an unglazed surface. A fixing that will not age-harden or deteriorate with time.
