Huskie's CN-258 is used for service entrance connections up to 4/0, and its bypass cartridge assures all compressions. A two-stage, rapid advance pumping system saves compression strokes and time. The nest dies are D-3, and can be changed with other Kearney "O" type dies. If you wish to use Burndy "W" type dies, simply slip the “W” type over the D-3 nest die and snap them into the locked position.
