In a 6 x 7 rope,
the wires are larger than those of other constructions
of the same diameter. Wires of a 6 x 7 are approximately
twice the diameter of outer wires of a 6 x 25 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
6 x 7 rope construction is made with fiber core and
right regular lay.
