Solid Braided Cord: Strands pass under, then over the others while rotating in the same direction for a smooth, uniform surface.

Double Braided Cord: A hollow single braided shell around a braided core Diamond Braided: Tightly woven braided shell around a braided core

Twisted Rope: Two or more parallel strands rotate around an axis in one direction for added strength and smoothness.

Caution-Never Exceed 20% Of The Breaking Strength For Working Load.
