A drywall corner bead which includes a plurality of integral preformed barbs provided at intervals along the length of the corner bead for securing the corner bead to a drywall corner. The corner bead includes first and second longitudinally-extending flanges which are interconnected by a longitudinally-extending rounded nose, and the first and second flange are disposed at an angle of less than 90.degree. with respect to each other. The barbs project inwardly from the flanges in a generally perpendicular direction and have a length of less than about 3/32 of an inch. When the corner bead is applied to a drywall corner, the barbs penetrate substantially only the paper layer of the underlying drywall and secure the corner bead to the corner. The drywall corner bead can be rapidly applied to a corner without requiring additional tools or materials, and the corner bead is securely affixed to the corner by the barbs until the corner is finished with joint compound and paint.

[ I claim:] [1.] A drywall corner bead comprising:first and second longitudinally-extending flanges which each include inner and outer edges;a longitudinally-extending rounded nose which interconnects said inner edges of said first and second flanges, said first flange being disposed at an angle in a range of 70 to 80 degrees with respect to said second flange so that the first and second flanges form a substantially acute corner in an uninstalled condition of said corner bead;a plurality of integral preformed barbs provided at intervals along each of said first and second flanges in a generally perpendicular direction, said barbs of said first flange being in transverse alignment with said barbs of said second flange;each of said barbs being interconnected to said flanges by an integral bent portion and being positioned adjacent to a hole in said flange, each of said holes including a pointed tip opposite from said bent portion of said barb, said pointed tip being directed toward said inner edges of the flanges.
