Stopper Knot A stopper knot is tied at the end of a rope to prevent the end from unraveling, slipping through another knot, or passing back through a hole, block or a device.

This version, the Ashley Stopper knot, also known as the Oysterman's stopper, is a knot developed by Clifford Ashley around 1910. It makes a well-balanced trefoil-faced stopper at the end of the rope, giving greater resistance to pulling through an opening than other common stoppers. Essentially, the knot is a common Overhand noose, but with the end of the rope passing through the noose eye, which closes upon it.

Also see the Double Overhand Stopper Knot.
