  • Leveling tool
    Patent number: 6732441
    Abstract: A leveling device for a construction material surface surrounding a drainpipe presents an elongated beam having a central seat therein for reception of the end of a drainpipe therein. Upon a seating of the drainpipe, a pair of opposed inclined surfaces contact the construction material surrounding the drainpipe. Rotation of the beam about the drainpipe presents a smoothed, inclined surface about the drainpipe with the excess poured material being collected in pockets in a sidewall of the device. The depth of the inclined surfaces below the drainpipe top can be regulated. Bubble levels assure a proper orientation of the beam during rotation.
