Parachute Cords Information
December 30, 2007 |
Also called paracords, parachute cords serve as the suspension lines of parachutes. They are usually made of nylon – the same material used in ordinary ropes – but are specially constructed to make them tougher, thicker, and less prone to tearing and rotting.
Remember that your safety depends on how well your parachute cords can support your weight. How do you know which one to choose? Here are some tips to help you.
Weight support
An important factor in choosing paracords is their weight capacity. This mostly depends on the number of nylon strands present in the cord. Cords are classified as Type I, Type II, Type III, and Type IV. Type I, the lightest variety, can support up to 100 pounds and has five nylon strands. Type IV is a heavy-duty paracord with coreless construction, which means the entire cord is made from braided nylon for a more solid rope. The most reliable paracords have a tensile strength of #550.
Weave quality
Although nylon is highly durable, a poorly woven rope can still easily give in to your weight. Make sure your paracord is tightly braided throughout with no loose strands or bumps. The braiding should stay in place even under sudden pressure. A single loose strand can pull on the entire cord and cause it to break.
Tensile strength
Paracords that have tensile strength of around 550 can support heavy weights and will not break under immense pressure. Cords with lower tensile strength should be used in multiple strands to increase their weight capacity.
