Description Design The Universal Closures consist of two plastic end caps type (description see on page 80 f.) and a plastic closure tube. The longitudinally split closure tube is closed with two plastic bars. They are pushed on by using only a plastic hammer and are secured with pins. For re-entry also only a plastic hammer is required. Permanently elastic longitudinal and round sealings allow the closure to be opened and re-closed as often as required without additional installation material. The round sealings are applied pre-cut with a joiner in order to allow installation on uncut cables or on rehabilitation purpose. The two end caps incorporate the strain relief absorbing mechanical forces which may be applied to the cables from the network side. Two metal bars interconnect the two end caps. On the lower bar the fiber management system is installed. Application The family of Universal Closures type is designed to protect splices and to store excess buffer length inline to fiber optic cables. The closures are applicable in all network types such as aerial, duct or direct buried networks as well as in all network levels such as interconnection, branching, distribution or access levels. Features Suitable for all network applications in inline configuration on cut and uncut FO cables Fast and easy access to the splice without special tools Fast and easy insertion of branching cables on demand without special tools Choice of complete closures including one of three different fiber management systems Different sizes for up to 540 splices Same installation procedure for inline () and canister closures (UCNCP, see page 87) All closure sizes are available with three different fiber management systems included in the pack. Each closure is equipped with a feedthrough for external grounding or valve for pressure tightness testing (flash test).

Accessories for Universal Closure Family Splice Trays Standard Splice Trays For storing of mechanical or fusion splices as well as excess fiber length. Two buffer tubes can be fixed at each of the four entries of the tray. For easier access at a future time it is recommended to store a maximum of 2 single fiber splices. The fiber excess length should be 200 mm and is stored in the the tray. With bending diameters between 60 and 80 mm it is guaranteed that the stored fibers are free of any stress and attenuation increase. For fiber management type "E" with single tray access, each tray has to be protected by the transparent cover which is snapped onto the tray. For storing the splices in the Standard Splice Tray, splice organizers are required (see next page). VIP Splice Trays VIP Splice Trays are used for VIP Fiber Management.
