It achieved a tensile strength of 250kg by making the stainless steel inner wire part more than 7pcs. high density 7 x 7 stainless steel wire. It applies swaging to the surface, and it reduces the coefficient of friction and achieves a light lever touch. It adopts aluminum die casting which enables high strength and quality improvement at the joint part of Tyco. It uses OEM equivalents as the most important fitting hardware of the parts making up the wire.
