ABSTRACT:
A detachable handle for use on erasers having absorbent material attached to a flat, rigid backing plate such as the common blackboard eraser. A "C" shaped rigid strap contains "C" shaped notches in the ends thereof. These notches are disposed to face one another and to engage opposite edges of the eraser backing plate. The notches are sized to frictionally retain the backing plate thereby providing a handle to control the eraser during use.
