3M One Step Closure (OSC) for low-pair copper cable splices ™

3M One Step Closure (OSC) for low-pair copper cable splices ™
3M™ One Step Closure (OSC)
for low-pair copper cable splices
3M™ One Step Closures (OSC) are one-piece, tool-free, one-hand/one-operation,
small size, mechanical, copper cable splice closures. Simply by pressing the two
shelves of the closure together by hand, the closure locks and seals the splice.
Closure body is made out of UV resistant thermoplastic material and the sealing is
a patented gel. Splice area in the middle of the closure is non-filled and the sealing
material is surrounding the splice cell. Top shelve and bottom shelve of the closure
3M™ One Step Closure (OSC)
are hinged from the back edge and when the closure is closed, sealing gel on the
top and the bottom shelves meet/compress each other sealing the cable entries
automatically. The design of the closure allows re-entries by simply unlatching the
locking mechanism.
Applications
3M™ One Step Closure-Small (OSC-S) and the One Step Closure-Large (OSC-L)
have similar features in terms of sealing properties and application area. The
difference is the closure size and the splice capacity. OSC-S closure is mainly
for two- to four-pair splice (with 3M™ Scotchlok™ Connectors) protection and
OSC-L closure is mainly for up to 10-pair splice (with 3M Scotchlok Connectors)
protection. OSC-L can also be used with a 10-pair 3M™ MS2™ Module. They are
Inside of 3M™ One Step Closure (OSC)
designed for aerial applications in Outside Plant and in buildings where bonding
isn’t required. Closures are typically used as 1 cable in/1 cable out in-line splice
protection. OSC-L and “one cable in two cables out” versions of OSC-S can also be
used for branching. OSC-L is suitable for wall fixing.
