Abstract: A crosscut fixture for a table saw which includes a flat board, a guide rail which is fixed to the bottom surface of the board, and an elongated guide bar which is pivotally connected to the top surface of the board for enabling the guide bar to move relative to the board to a plurality of angular positions relative to the saw blade. The fixtures provided with a clamping device for locking the guide bar to the board at any desired angular setting. The guide bar is also provided with a length gauge and the board is provided with an angle scale which is intersected by the rear surface of the guide bar. The angular position of the guide bar relative to the saw blade is determined by aligning the lower edge of the rear surface of the guide bar at the appropriate angular marking on the scale. The guide bar is also provided with a length gauge at one end.
