Calibrated Crack Monitor

Crack Monitor consists of two overlapping acrylic plates. One plate is white with a black millimeter grid; the other is transparent with red crosshairs centered over the grid. Once the Monitor is secured with epoxy or screws across a crack, the crosshairs shift vertically or horizontally on the grid, making crack movement easily visible and trackable.

5-Minute® Epoxy is a rapid-curing, general-purpose adhesive/encapsulant. Bonds rigid, durable substrates such as metals, glass, ceramics, concrete and wood in all combinations. Forms a clear, hard and rigid bond or coating in minutes.
