ABSTRACT:
A system for providing a visual body-length indicator for a group of mine roof stabilizers of various, unique lengths includes providing each stabilizer with a tubular body and a slot along the body. A bottom annular ring having a ring gap formed therein is attached to the body, with the ring gap and body slot being oriented in a unique relation for each unique body length, providing a visual indicator of body length that can be observed from a distance, even after the stabilizer is installed into a drill hole in a mine roof.
