ABSTRACT:
An electrical fitting with an improved arrangement on the trailing end for securing an electrical cable to a panel or an electrical box. The electrical fitting may include a single bore on the trailing end for connecting a single electrical cable to a knockout or two bores for securing two cables to a single knockout opening. The electrical fitting include a connector body having a leading body portion and a trailing body portion. The leading body portion may include a snap ring for snap-in connection to the panel or box or a threaded nose portion and locknut. The trailing body portion may include one or two inlet bores therein for the insertion of electrical cables. The improved arrangement for inserting a cable on the trailing end of the fitting includes an improved tandem tang with a common middle portion and a leading and trailing tang extending therefrom. A portion connecting the trailing tang to the common middle portion is of arcuate shape. The improved tandem tang enables easier insertion of electrical cables within the trailing end of the fitting.
