Crack Width Ruler

Description

Crack Width Ruler is a simple gauge that has been designed to provide inspectors with a low-cost alternative to a graduated microscope for determining the width of a crack in concrete or other building materials. Selecting a location where the edges of the crack are reasonably straight and parallel, hold the Crack Width Gauge in contact with the crack (at right angles to the crack). Align the Crack Width Gauge where the calibration and the crack are the same width. Record the width, length and location of the crack.
