Scratch-A-Track Motion Monitor

Scratch-A-Track Motion Monitor tracks thermal movement, structural settlement, load-induced deflections, and other changes in relative positioning. The monitor is compact, lightweight and weather-resistant, and designed to provide a clear, continuous graphic record of the total relative movement of adjacent surfaces.
