Extension cord repair.

I had a cut in the jacket of my extension cord. The wires were all intact, but I didn't want to use electrical tape to repair it, since it just isn't very durable. I learned of a heat shrink repair method that I decided to adapt myself. I had some adhesive lined heat shrink tubing, which I cut two lengths and sliced each piece down along the length. I then wrapped the cord with both pieces such that the seams were on opposite sides of the cord. I then zip tied along the lengths of the shrink tubing to secure them during the heating process. It worked beautifully! The cord is now sealed from the elements, and the repair will last as long as that cord does.
