  • Method and apparatus for corner bead angle enlargement
    Patent number: 5311760
    Abstract: This invention relates to a drywall corner bead spreading tool. It is a portable handheld device for quickly and easily increasing the included angle between the corner bead wings from 90.degree. to 135.degree. safely without bending or kinking. Corner bead splicing can now be eliminated in construction situations requiring the larger included angle and 10 feet ceiling height lengths. The device taught by this invention is simple to use and can be made nearly indestructible using 14 gauge steel.
