Cable housing (often referred to as the outer cable) is 3/8 inch in diameter and has a white nylon inner sleeve in order to reduce friction and to protect the cable from wear. The nylon white inner sleeve has been swaged together with the main housing using the steel end as shown: Note A
Note B: When the housing is tied into a knot, the white nylon inner slides into the main part of the housing at the cut end (opposite end of steel end). If the cable housing is cut to size by first tying it into a knot; then when the knot is released, a part of the nylon white inner will be left protruding.
