The parachute cord, also called the tendon, serves as the suspension line for the parachute. These cords are usually made of nylon — the same material used in regular ropes — but nylon paracord is specially designed to make it stronger, thicker, and less prone to tearing and rotting.
Remember that your safety depends on how well your parachute rope can hold your weight. How do you know which one to choose? Here are some tips to help you do that.
Tear Strength: The top-quality nylon paracords, which have a tear strength of about 550, will withstand heavy loads and will not break under high loads. A rope with a lower tensile strength should be used in multiple threads to increase its strength.
Mesh Quality: Although nylon is very strong, poor knit webbing can easily give way to your weight. Make sure your paracord is tied tightly throughout without any loose threads or bumps. The braid must stay in place even with sudden loads. Loose threads can pull and tear the entire cable.
Heavy Maintenance: An important factor when choosing a paracord is its durability. This mainly depends on the number of nylon threads that are in the line. Cables are classified as Type I, Type II, Type III and Type IV.
Type I, the lightest option, can withstand loads of up to 100 pounds and has five nylon threads. Type IV is a heavy paracord with a coreless construction, meaning the entire cable is nylon braided for a stronger rope. The most reliable Paracord has a tensile strength of #550.
