Abstract: The present invention features a dispensing roll that has a string of tandemly-placed, tear-away, repair articles of manufacture. These repair articles each have an inner, mesh member that has a peripheral member consisting of finishing tape border that is fastened to and placed about the inner, mesh member. The repair articles are intended to be used to repair damaged drywall or plasterboard areas surrounding an electrical box, such as a receptacle box, a switch box or a junction box. A repair article is torn from the end of the dispensing roll along perforations that are provided between each article. Any cracks, holes, saw lines and blow-outs surrounding the electrical box are filled in with compound. The article is then placed over the hole in the drywall where an electrical box is located. The outer, tape border is sufficiently-sized to cover the damaged areas about the electrical box. The damaged areas are then finished off and coated with paint primer.
