Abstract: The unit for retaining/securing a fiber optic cable comprises an enclosure including a tray having a back base plate, a top and a bottom sides and a unit for retaining/securing a fiber optic cable, disposed in an interior of the enclosure. The bottom side is provided with a pair of identical apertures. Each aperture resembles to a flat shovel having an upper rectangular shape continued by a circular sector; the aperture is so profiled as to engage alternatively a biting-retaining fixture for inserting a cable or an exit grommet for a leaving cable; the former is made of a rigid plastic, while the second—of a soft, elastic polymer. The unit for retaining/securing a fiber optic cable is actuated by a shifting lever, having a shape of an angled, cantilevered part with a longitudinal axis of symmetry bent generally at 90 degrees.

Abstract: A flat plastic structure is provided with several horizontal, parallel rows of openings, each comprising several single, for horizontally attaching openings, alternating with several double, for vertically attaching openings. Each of the several single, for horizontally attaching openings has an upper and a lower wall converging inwardly from horizontal edges of those several openings. A flat bar for horizontally attaching centrally connects opposite vertical walls of each single opening. A double, for vertically attaching opening incorporates a vertically extending, centrally located apex-shape structure formed by a pair of intersecting walls diverging towards the back side. A flat bar for vertically attaching is located at each side of the vertically extending centrally located apex-shape structure connects opposite vertical walls of the double, vertically attaching opening.
