The ROCK-IT is an easily installed device used to measure displacement in two horizons about mine roadways. The layout and size of the reading indicators allow for fast, accurate and continuous measurement of strata movement.

Two reading indicators, L (lower horizon) and T (total movement) are connected by stainless steel wire to anchors located up the hole. The lower anchor is attached to the L (lower) indicator and the upper anchor, usually placed above the anticipated height of softening, is attached to the T (total) indicator as shown.

The T (total) indicator is graduated in both 5mm black blocks or 2mm graduations and can record up to 150mm movement. The L (lower) indicator is graduated in both 5mm black blocks or 2mm graduations and can record up to 75mm of movement.
