The two sides of the U-shaped clamp will frictionally grip the adjacent sides of the stud and each clamp side has inwardly extending barbs which will dig into the stud and prevent the removal of the clamp therefrom. In addition, the web portion of the clamp has an inwardly extending pointed prong that will enter the stud and prevent any vertical movement of the clamp and outlet box with respect to the stud.
