The vast majority of this market utilizes a 6x7 Bright Fiber Core. In a 6x7 rope, the wires are larger than those of other constructions of the same diameter. Wires of a 6x7 are approximately twice the diameter of outer wires of a 6x25 FW rope. The large size of the outer wires gives this class excellent abrasion resistance –at great sacrifice of bendability and resistance to fatigue. The standard 6x7 rope construction is made with fiber core and right regular lay.
