The underwriter's knot is used in electrical wiring as strain relief to prevent a cable from being pulled from electrical terminals when the cable is yanked.[1] Clifford Ashley listed it as an electrician's knot in 1944. He suggested it be used "where rough treatment is expected" and described it as a two-strand wall knot.[2]
