Crack Monitor - Standard

Product Code: CMS-001

The Crack Monitor consists of two overlapping acrylic plates. One plate is white with a black millimetre grid, while the other is transparent with red cross-hairs centered over the grid. Once the Crack Monitor is in position across a crack, the cross-hairs shift vertically or horizontally on the grid if movement occurs, so that anyone can easily see and track crack movement.  Complete with fixings & instructions.
