Effectively
Protects Cable
The BLACK-JACK 25-Pair and BLACK-JACK™ Plus 50-Pair Closures are filled with
POLY-BEE™ Sealant to provide long term
protection for direct buried cable splices (individual or modular connection).
The sealant is designed to form a barrier to protect splices against the harsh
elements
of nature.
The closure designs incorporate a water-block system that consists of a soft
cable grommet and a gasket seam seal. The soft grommet is designed to
effectively seal around cables within the accepted diameter range. The gasket
seals the halves of the closure to further ensure protection.
Two Designs Available
The BLACK-JACK 25-Pair Cable Closure is available in both the traditional butt
splice version and the in-line splice version. The 50-pair cable closure is
designed to incorporate both butt and in-line capabilities with one design. The
in-line version can be used for straight through or branch splice applications.
Both designs offer the same reliable service, are easily re-entered and must be
replaced
after re-entry.
No Resin Required
The one-piece closure shell is shipped with the entire water block system in
place. The unit is pre-filled with POLY-BEE Sealant so there is no resin mixing
required. Without resin, preparation time is greatly reduced. Set-up time
is also eliminated. This means the closure can be buried immediately after
installation. Working without resin eliminates toxic material concerns and
inventory waste because shelf-life is never an issue. Fast, Easy
Application
Several design features make installation easy. The hinge on the shell is flexible allowing the closure to be squeezed shut by hand. The flexible hinge is
also helpful during re-entry.
The closing clamp which slides over the closure flanges has a V-notch on the
back to make initial hand installation easier. A narrow horizontal slide along
the closing clamp provides leverage to bring the halves together. The kit comes
with bonding hardware that fits over the studs of the bond connectors to
provide shield continuity. This bonding hardware also assures proper alignment
of the cables in the closure. |
