These low-profile phone jacks have “snap-in” PC mounting,
right-angle plug insertion and available with 2- and 3-conductor
circuits and plastic or metal bushings. Ideal for telecommunications,
data processing and other high quality audio connecting
applications.

plastic housing. Only .375" high, this jack features a plain
(non-threaded) bushing and accepts commercial standard phone
