  • Carpenters square with elevation attachment
    Patent number: 6327786
    Abstract: A carpenter' square provides a pair of I-shaped legs joined at right angles, each of the legs having a pair of back-to-back U-shaped channels preferably of a size for accepting a construction material, such as common 2×4, 2×6 and 2×8 lumber boards. The lumber may be inserted snugly into them so as to align the lumber at right angles. The square also may include a gusset plate for mounting the square onto a construction stake at any selected height and direction so as to enable the defining of a corner and its related orthogonal directions.
