550 Cord - AKA Paracord or Parachute line will support human weight. While Testing and practicing knots I use 550 cord. It best simulates a dynamic rope. A Figure 8 on bight to form the loop and double bowline on the top for anchor over a 4.5 foot cord has supported my 230 lb body. However, the knots are extremely hard to get out after weighting.
Not to mention that the line is truly about 2.5 - 3 mm when weight and there would be no way to generate enough friction to safely rap to the ground. Also due to the diameter over a sharp edge there is no give so that would be bad and would end up in a cut line.
All in all do not rap with a 550 line. It is a bad Idea. Instead keep it as accessory line it works for a whole lot of stuff. Just not rapping.
Plus when sky diving they have nearly 30 to 40 strands of 550 cord to hold the canopy open and keep you in the sky.

No way to generate enought friction? Shit a single caribiner is all the equipment you need. Just wrap it around 5 or 6 times and you should get decent friction.
Something similar was done by a guy off this forum rapping off a single strand of nylon core from a dynamic rope.

In reply to: No way to generate enought friction? Shit a single caribiner is all the equipment you need. Just wrap it around 5 or 6 times and you should get decent friction.
Again that could still spell funeral. So many wraps = High friction/heat. That cord could snap, as well the friction from the brake hand wouldn't be sufficient for a novice rapper.
I work for a Sergeant who is working on master certification in rappelling. I hooked him in Aussie on 11mm super static double wrapped on biner (Normal Tactical Set-Up). we went off at 10 feet to practice a drill. The rope spun and opened the screw gate. It unclipped one strand thanks to god. So 190 lb Sergeant ziplining to me on belay. He was lucky.

That is correct.
There is also 550 cord as well, which is weaker over para cord.
550 cord is approximately 7mm dia loosely woven nylon cord.

I just measured the 550 cord that have and it's about 4 mm. and before you say that I'm wrong it's the same cord that we get from the NAVY supply system

I'm sure you didn't mean any harm and I know you, Aric, like to break things and have the smarts to do things with relative safety - but threads like this are a patently bad idea in a place like RC. There are enough lurking edge cases and people who won't, don't or can't think things through to be putting up threads that give the suggestion that marginal or unsafe equipment and practices are ok or accepted within our community. My two cents anyway - I think the thread go away.
P.S. Four hybrid Aliens are on their way to you...

I was just as shocked as you when I found that cord and DO NOT recommmend it in any way shape or form to rap off of.
It was always a "I can't beleive that someone is selling this stuff for rappelling purposes" post. Somehow it became a troll which was not my intention.
DO NOT RAP ON 4MM CORD
