3M™ Splice Protection Products – Copper Closures & Terminals

3M™ copper splice protection products include closures & terminals that can be used in buried as well as aerial applications.

3M™ OSC Closures
The 3M™ One Step Closure Small (OSCS) and One Step Closure Large (OSCL) are two low pair-count copper cable splice protection closures that are simple to install and easy to re-enter. The cylindrical design is ideal for overhead and underground applications of 2 / 4 pairs up to 10 pairs combined with 3M™ Scotchlok™ Connectors UYUY2 series and/or 3M™ MS2™ 10-pair Modular Splicing.

3M™ Distribution Closures BDR
The BDR is an underground distribution closure, designed to terminate up to 20 subscribers (10 drop cables) while allowing 20-pair distribution cables to go through the casing. It has a versatile design that works well with some of the 3M™ IDC technologies to satisfy the connecting and distribution needs of the network.

3M™ SLiC™ Aerial Closures and Terminals
The single-piece, double-walled aerial closure is installed in construction or maintenance situations. The one-piece construction permits complete splice access, without removal of the closure or bonding of the cables. The closures are free breathing and suitable for straight, butt and branch splices of non-pressurized communication cables. The interlocking ends make the SLiC aerial closure expand and meet any size sheath opening without special kits, eliminating excess inventory. SLiC aerial terminals have a spiral / rubber end seal and distribution terminals have closures with a lightweight, double-walled, molded-plastic housing, designed for fixed-count termination of aerial drop wires.

3M™ Dome Closures
3M™ Dome Closure is a cost-effective method of protecting butt splices for pedestal, hand hole or pole mount applications that has re-enterable PST dome closures. The closure provides protection from the harmful effects of moisture, insects and ultraviolet light, while providing easy re-entry. The splice is enclosed in a split polypropylene dome, clamped together with a steel latch and sealed with an o-ring. An expanded ethylene propylene rubber tube (PST) is slipped over the base of the enclosure to a gel sealing collar.
