Blue Wave Dyneema Rope Ball Terminal, also known as a Stem Ball or Elephant's Foot, manufactured from polished AISI316 marine-grade stainless steel.
Blue Wave has developed a range of rope terminals to complement the advantages of Dyneema® and Vectran® lines for running and standing rigging.
The Blue Wave Technical Team has designed a unique internal bail (also known as a bone or former) for the line to pass around and back into the locking tuck and splice.
