    Patent number: 5155303
    Abstract: A closure (20) includes a grommet (50) having passageways (52-52) therethrough for allowing cables to extend into the closure. The grommet (50) comprises a unitary elastomeric body (60). Each passageway is defined by an interior sidewall from which a plurality of longitudinally spaced circumferential ridges (74-74) extend. For a substantial portion its circumference, each ridge has an axis of projection which forms an oblique angle with respect to a longitudinal axis of the associated passageway and is sufficiently elongated in longitudinal cross section so as to be capable of flexing with respect to the axis of projection during insertion of a portion of a cable and enlarging its opening diameter to accommodate and form a seal about the inserted cable portion.
