Jacks are standard 2- and 3-conductor phone jacks with extra long
threaded bushing for mounting in panels/chassis up to 1.25" thick.
Metal bushing virtually eliminates hum pick-up, and is ideal for electric
guitar and speaker connections. Jacks mate with standard
commercial phone plugs. See plug section for mating plugs. Jacks
mount in a single .469" diameter hole. Rugged cable clamp protects
connections from twisting and pulling stresses.
