Abstract: A multiple telephone jack slide assembly includes a jack support member for supporting a multitude of telephone jacks upon an electronic wire connecting system. The jack support member is molded from resilient flame-retardant plastic and includes a channel formed by a rectangular-shaped, elongated slotted aperture. The telephone jacks include side walls which slidingly engage edge portions of the slotted aperture to support the jacks within the channel.
