The patented SMM Safety Directional Lines (life lines) are made of flame resistant, non-conductive, polypropylene rope and meant to be used as an escape route.  MSHA accepted, our SDLs are available with six different reflective tape colors for our SMM Tactile Signals - blue, green, orange, red, white, and yellow.  Customized to your needs, there are various combinations available.
