Three Acrylic Wall Crack Monitoring Gauges

Track visible crack movement over time with three acrylic monitors that provide a repeatable reference at the crack.

✅ See change against a fixed reference - Overlapping grid and indicator plates show relative horizontal and vertical movement.

✅ Compare more than one location - Three monitors let you keep records at separate points of interest.

✅ Make repeat observations easier to record - A visible scale supports dated readings and photographs from the same reference.

Build a record of movement

A single photograph shows how a crack looks today. A monitor adds a reference that helps you compare later observations with the starting position, making a sequence of dated records more useful.

Install each monitor according to its instructions, record the initial reading and use the same observation method thereafter. The gauge indicates movement; it does not diagnose the cause or certify that a structure is safe.
