These 2-pin connector plugs were originally manufactured for the antique radios listed in each product description. They maintain correct pin alignments and reliable signal transfer for original chassis wiring and auxiliary connections.

Featuring a 3/4-inch round body, this plug utilizes polarized pin sizing—a 1/8-inch small pin and a 5/32-inch large pin—spaced 3/8 inches apart center-to-center to prevent incorrect pin insertion during assembly or service.
