Trick - How to use Isolierband in a narrow place

[hemmjo]

That is a good trick, been doing that for years when heat shrink cannot be used. It is also better to start the wrap in a spiral along the wire. You also have to be sure your fingers are not dirty or you ruin the stick on the tape, However, I suggest that you used better quality tape. I NEVER use tape if the manufacturers is not willing to print their name on it.
