The original premium ultra-lightweight hollow braid cord.
 
"AmSteel®Blue is a torque-free, 12-strand single braid that yields the maximum in strength-to-weight ratio and, size-for-size, is the same strength as steel—yet it floats. AmSteel®Blue is an excellent wire rope replacement with extremely low stretch and superior flex fatigue and wear resistance."
 
This cord has an average strength of 2500 lbs (1100kg) and a minimum strength of 2300 lbs (1000kg). It is Available in Black and Silver.
 
Price per metre. Multiples are sent as one length unless you specify differently.
