Or is it left out to receive the beneficial rays of ol' Sol? The sun will bleach every other color, but white he will turn to yellow.

It is always hangared.

Your photo showed what I suspected. The factory attaches a metal alloy button head on the end of the cable by some process. I suspect this is done by pouring molten alloy (probably lead/tin alloy) in a small mold around the cable and then cutting the cable off. I cant do this so I will have to come up with another method. Ill think of something! Thanks Hugh
