Commonly Retro-Line systems are installed into a pipe from within a building and as such the intersection point of the heating cable and the pipe is located within an accessible dry space.

Listen to the December vlog and learn directly from a Heat-Line specialist about a unique method of intersecting a Retro-Line in an outdoor application that will allow it to remain accessible. Click Here to view the outdoor intersection document mentioned in the video.
