ABSTRACT:
A closure for optical fiber cables has a cover member and an end plate having an O-ring seal for sealing the end plate to the cover member by means of over-center latches. The inner surface of the end plate has a backbone member to which are mounted a fiber organizer and splice tray, a cable sheath grip, and a central strength member anchor for use with cables having central strength members. The end plate has openings for grommets through which cables pass into the interior of the closure, and a grommet and port plug retaining member fits over the outer ends of the grommet or grommets or grommet and port plug. The backbone member, which may be integral with the end plate, has a wall and flange portion that bears against the inner end of the grommet or grommets toward the closure interior. A threaded stud is connected to the backbone member and passes through the end plate and the retainer member, and a clamping knob threaded onto the stud enables tightening of the retainer and backbone against the ends of the grommet or grommets to insure a high degree of sealing of the interior of the closure from the exterior ambient atmosphere and water, and also from the effects of interior air pressure.
