The Sterling Depth Gauge comes with an English and Metric Rule as well as a depth rod. The rod can be used when the ruler will not fit in the opening that you are trying to determine its depth. To use the Depth Rod, you must extract the Ruler from the clamp screw slot and then rotate the clamp screw 90 degrees to the hole in the clamp screw. You can then insert the rod.
