Stop and Clamping Squares can be used in the same manner as a stop or combined with other elements to form more complex fixtures. Oblong slots enable a range of adjustable options. The DCT 200mm L Stop and Clamping Square with fine scaling on both sides serves as an adjustable angle. The combination of system boreholes and the oblong slot facilitates multi-functional use. The additional top plate provides further combination options in connection with other squares, or to incorporate tools like prisms or clamps.
