So I've had this question before and finally see a perfect example of it written out and can share.
I was looking at the Kestrel Flex and at the bottom of the description it lists out all the strengths of the webbing and such.
---------------------
Component Specifications
Belt structure and seat frame: 1 3/4” nylon parachute webbing 6000 lbs
Belt buckle: ADF 1 3/4” Raptor buckle 18kN (4050 lbs)
Leg straps and webbing bridge: 1” nylon milspec flat webbing 5600 lbs
Leg strap buckles: ADF 1” Raptor buckles 4000 lbs
Carabiner on webbing or rope bridge: Fusion Essence autolocking 28 kN (6300 lbs)
Rope bridge: Samson Predator 11 mm double braid climbing rope 6000 lbs
Prusik cord: 10 mm polyester 2760 lbs
------------------
So the belt can support 6000 lbs.
BUT
the prusik cord can only hold 2760.
Now I know both are very high (though I think with a fall and some distance, you easily approach the cord number)
So isnt really this entire setup limited to the cord strentgh of 2760? I mean, if you fell, and the prusik grabbed you, isnt that the weakest link?
