    • The present invention relates to a device designed to be used in repairing a hole in a wall, door, or other structure. The device includes a male member threaded into a recess in a female member with an umbrella-shaped device mounted on the male member and initially stored within a recess in the female member but released therefrom when the male member is unthreaded from the female member whereupon the umbrella device spreads outwardly to cover or obscure the opening. Break points are formed on the male member to allow the shaft thereof to be broken off after the device is properly positioned.
