ABSTRACT:
A multi-face clamp for wood working which comprises a clamping unit including a plurality of corner pieces. Each of the corner pieces defines at least two pressure faces which are adapted to engage complementary faces of a work piece. Two threaded bolts extend from and are operatively connected with the corner pieces. One of the threaded bolts has threads formed in an opposite direction from those of the other of the threaded bolts. A turn-buckle is disposed between each pair of adjacent corner pieces and receives in its inner threads the respective free end portions of the threaded bolts, so that upon turning of the turn-buckle the pressure faces of the corner piece exert pressure upon the complementary faces of the work piece.
