Below is a list of Elastic Cords manufacturers from Oakland, California. Elastic cord, often referred to as bungee cord, is a cordage variety that is manufactured to include a multi-strand elastomeric core. Fitting a cord with an elastomeric core gives the cord the ability to stretch well beyond its unstressed length. When two ends of an elastic cord are pulled in opposite directions, the cord increases in length, and the tension of the cord increases as length increases. This tension makes elastic cords a good material for securing cargo during shipping, particularly in small-scale hauling applications.
