CSD’s marine transit frames are designed to integrate seamlessly with NOFIRNO®, RISE® and SLIPSIL® systems, ensuring reliable fire, water and gas protection for grouped cable penetrations. Manufactured from high-grade materials and certified to international standards, they are trusted across naval fleets, commercial shipping and offshore platforms.

Multi-cable Transit Frames – Marine
Engineered frames for harsh marine environments. In marine and offshore environments, sealing systems face some of the toughest conditions – constant vibration, pressure fluctuations, saltwater exposure, and strict safety requirements. Multi-Cable Transit (MCT) frames provide the robust structural support needed to house sealing systems in bulkheads, decks, and other critical areas.
