The Avongard Corner Tell-Tale monitors horizontal and vertical movement across a crack in a corner.

The Tell-Tale is hinged enabling it to be used in internal corners of angles between 70 and 180 degrees. The Corner Tell-Tale monitors both internal and external corners.

Avongard Tell-Tales are precision gauges that consist of two plates which overlap for a part of their length. The bottom plate is calibrated in millimetres and the top plate is transparent and marked with a hairline cursor in the form of a cross.
