Abstract: A grip block for holding and immobilizing elongated cylindrical members, such as cables, has a base member having a central axis and first and second pivot arms, one mounted on each side of the axis. An actuating member has a body which has two or more cable receiving channels therein which are oriented parallel to the central axis and depending actuating pins for actuating the pivot arms to force one or more cables into the discrete channels. The base and actuating member are held together by means of studs within a splice closure or by both in conjunction with a mounting bracket.

Abstract: A ground lug insulator assembly having a base member that mounts to a ground lug stud projecting from a splice closure. The base member is cup-shaped and houses a wire connector therein which is connected to the ground lug. A cup-shaped cap member is adapted to mate with the base member and to latch thereto after both are filled with B-sealant gel.

Abstract: A preferred embodiment of the present invention includes a base member with first and second base portions that are angled relative to each other for aligning a longitudinal axis of the base member in a parallel relationship with a longitudinal axis of a pole. Preferably, first and second side walls extend outwardly from the base member for engaging mounting ribs of the splice closure. Preferably, the mounting ribs of the splice closure engage the bracket in a straddled configuration.

Abstract: An optical fiber cable splice closure has a base member and a cover mated therewith. The cover is extended to accommodate stacking large numbers of splice trays or splice holders so that the coverall capacity of the closure is increased over prior art structures. The extended cover has a plurality of longitudinal and transverse strengthening ribs molded integrally with the top and side walls of the cover. For increased resistance to outside forces, the top wall is bowed and strengthened and supported by the ribs both above and below the wall. In a second embodiment, the side walls are also bowed, as are the strengthening ribs.

Abstract: A mass fusion splice tray assembly increases the capacity of a splice closure which has support members thereon for supporting the assembly. The assembly include a splice tray which latches to a support member and which has locating slots to contain two splice holder inserts. A cover member has latching legs which latch to wedge shaped latches on the splice tray. The cover member is adapted for pivotally mounting a discrete splice tray on the top surface thereof so that the total splice capacity of the splice tray assembly is increased.

Abstract: A racetrack grommet of resilient material for use in providing a seal between two flanged closure members has first and second spaced sides thereon adapted to be positioned between the flanges, and transverse end sections having insert receiving members having bores therein. Insert members are configured to fit within the bores in end to end butting relationship to provide a seal between a cable entering or leaving the assembled closure and the insert receiving members which, in turn, provide seals for end openings in the assembled closure. The bores in the insert receiving members have holding and sealing means therein and each insert has mating means thereon for mating with the holding means to provide a seal between each of the insert members and the insert receiving member. One or more port plugs seal the unused bores in the insert receiving members.

Abstract: A mass splice tray for holding a plurality of optical fiber splices, such as mechanical or fusion type splices for optical fiber ribbons, has a floor and front and rear and end walls defining an interior of the tray. A support shelf extends from the rear wall into the interior, spaced from the floor, for supporting splice holders above the floor at one side of the tray. Extensions on the end walls define, with the rear wall, channels for routing fiber, especially ribbon fibers, into and out of the tray. Splice holder inserts have locating means thereon for mating with locating means in the rear wall to position the inserts on the support shelf, and splice holders are dimensioned to fit within the inserts. The elevation of the splice holders permits routing slack fibers or ribbons within the interior of the tray without interference from the splice holders. Protective tabs extend from the top edges of the walls to maintain the fibers or ribbons within the tray.

Abstract: An optical fiber cable splice closure assembly includes a base member and a mating cover which, when assembled, form a hollow splice closure with openings at each end. One or more cable gripping members are located within the closure adjacent the open ends for gripping cables passing through the open ends, and a cable strength member is located adjacent to, and aligned with, the cable gripping member. One or more elongated pedestals extend from the floor of the base member, each having latching means on the distal end thereof. A splice tray adapter plate is latched to the distal end of the pedestal or pedestals, thereby creating a slack fiber storage space below the plate. The adapter plate can pivotally hold two or more standard splice trays on one side thereof, or a discrete or mass splice tray on the reverse side thereof. A race track grommet member having insert receiving members on each end thereof form a sealing means for the closure when the base member and the cover member are clamped together.

Abstract: A central strength member anchor for use, for example, in a splice closure, for anchoring the central strength member of a cable entrant into the closure has a planar member having at least one upstanding leg at one end thereof. The distal end of the leg has clamping a strength member receiving member having a bore into which the strength member is to be inserted. The receiving member has clamping arrangement, such as one or more set screws, for clamping the strength member in the bore. The height of the leg is such that the bore in the receiving member is substantially axially aligned with the cable strength member. The planar member has locating holes therein for locating the anchor in the closure, and side walls depending from the planar member have slots for mounting the anchor in the enclosure. The side walls also have at least one slit therein and the planar member is scored so that a portion of the anchor member may be broken off to shorten it.

Abstract: A grip block assembly for gripping cables or other elongated members has a substantially hollow frame member having openings in the walls thereof to allow an elongated member to pass therethrough. First and second lever arms pivotal on the same axis are adapted to be pivoted in a scissoring action to grip a portion of the elongated member and to force it into contact with a gripping surface on an actuator block which is reciprocally movable within the hollow frame member. The actuator block has depending members which contact the lever arms for causing them to pivot with respect to each other, and a captive bolt held in place by a cap on the frame functions to move the actuator block.
