Below is a list of Ropes manufacturers from Northridge, California. Ropes are woven or twisted cordage varieties that have been used as hauling, suspension, watercraft mooring line and in many other capacities since before recorded history. Ropes are composed of fibers that are twisted together. Those twisted fibers are then twisted together to make strands, which are then twisted or braided together to create rope. The direction that the fibers are twisted is often opposite of the direction in which the strands are twisted in order to cause internal friction, which reinforces the rope's strength.
