#6, 3/16×500 Solid-Braid Nylon Spool

Solid Braid Nylon Extra is made to the highest
standards. This is a firm round cord which is great for use in applications
involving blocks and pull. The cord has very good shock load resistance, as
well as rot resistance. We use a lock stitch construction which prevents the
cord from unraveling when cut. This product also holds a good knot.
