The crack width gauge is designed to allow you to quickly check the width of a crack by hand, to determine how wide it is. It is transparent and flexible, making it easy to hold over a crack and photograph it. It features a scale ranging from 0.05 to 3.0 mm (with markings at 0.05 and 0.1 mm intervals) and extends up to 86 mm. Surface scratches may appear on the crack width gauge as a result of the manufacturing process and normal use.
Dimensions (L x W x D) 86 x 54 x 0.76 mm (dimensions may vary slightly) with rounded corners.
