Our TXT cables are 100% made and manufactured right here in AMERICA. The only cables you'll find that are produced with adhesive lined shrink tube to prevent infiltration by moisture due to the capillary action the results with standard heat shrink. This heat shrink is clear so that you can visually verify the condition of the connection. Why hide behind a black or red opaque heat shrink that hides the quality of the connection?
