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.
The Scratch-A-Track Motion Monitor is mounted over a crack, joint, or another void, and anchored with user-supplied concrete screws. When mounted, the spring steel finger and thumb screw assembly allow pressure to be applied for scribing onto the HM-643 Scratch-A-Track Monitor Recording Pads (purchased separately) for use.
