The double overhand noose is a very secure hitch knot. It might be used by cavers and canyoneers to bind a cow tail or a foot loop to a carabiner.[4]

Double overhand noose binding carabiners.[a][b]

Details

[edit]

A heavily tightened double overhand noose will jam. The bound object has to be removed before untying.

As the double overhand knot, it neither slips nor turns around. However, a third round turn might be useful with some highly lubricious spectra/nylon ropes.[5]
