The heavy duty professional phone plug series improves on the design of the existing C series by offering the thinnest available A-gauge 6.35mm / 1/4" plug with unique Neutrik chuck type strain relief on the market. The slimline shell with a width of 14.5mm / 9/16" meets the most recent requirements for highest density jackfields (15.88mm / 5/8" jack pitch). The precise machined one-piece tip contact without rivets makes it unique and avoids hook up in a socket or break off the tip. The Plug X Series serves all applications such as guitar applications, audio cables, snakes, speakers, amplifiers and mixing desks.
