FEATURES
Modified Littel-Plug® phone plug, 2- or 3-conductor, with coupling ring that can be threaded to thread projection of mating panel jack or to threaded end of the Lock-Extension Jax®. Locks connection after plug has been fully inserted into its mating panel jack or Extension Jax®.
Lock-Plug® makes proper contact to mating jack without tightening or attaching coupling ring, when rapid disconnect may be desired. Lock-Plug fits any standard jack with 3/8".-32 thread bushing with .094 inches of the bushing exposed. Lock-Extension Jax also will mate properly with standard phone plugs, where no "lock" requirement exists.
