This 3-inch jack plug features a durable black insulating barrel paired with a standard 1/4-inch diameter shaft and tip. Designed for two-conductor (mono/TS) audio connections, it provides reliable signal transmission for vintage radio auxiliary inputs, head-set terminals, and patch cords.

The 3-inch overall length allows for a solid grip during insertion and removal, while the threaded barrel housing unscrews easily to access internal solder terminals and cable strain relief.
