Shock cord (or Bungee cord) is a great way to secure objects without having to tie a knot. Cords are inexpensive and can have a metal or plastic hook added to them. Elongation of the cord is usually twice the original length. There are many uses for this product, including commercial fishing, aviation, toy manufacturering, garment manufacturering, automotive, and general industry.
