550 parracord for climbing?

[CharlesHarris]

Paracord is not suitable for climbing rope or rappeling, although it is ok for rigging equipment tag lines and tethers.

Climbing ropes are usually 11-12mm in diameter, and tested to 1500-2000kg with a stretch factor of about 30-35% at rupture. There are various types designed for handling either static or dynamic loads. Depending upon your specific need and skill level, you need to research suitable rope for your intended purpose. Rope for lifting static loads is entirely different from life-safety line, which is intended to absorb energy from a fall and arrest a climber on belay without injury. Using the wrong type of rope canget someone killed.
