It comprises of two steel blocks A & B. One (A) having flat machined discs mounted on the X,Y, Z axes and the other (B) having matching machined discs through which the stem of a manual dial gauge can be placed to measure any movement in any axis.

The re-bar anchors on the bottom of each block are grouted adjacent to each other into the structure that is being measured.
