RGSFBO Ex
RGSFBO Ex is for bolting and installations where cables are already in place.
The bolted transits can be used in areas where welding is prohibited, or when the stress level induced by welding is unacceptable.
The system consists of a frame, rubber blocks and a compression unit.
The frame is bolted to a marine structure and packed with rubber blocks suited for each cable and pipe dimension. The compression unit is inserted to compress the rubber blocks against cables and pipes to establish a tight seal.
Benefits of MCT Brattberg Ex systems
- Ex rated transit for hazardous environments
- Assists cable management
- Seals the penetration against the passage of fire, water, gas, sound and environmental hazards
- Can be combined with special EMC modules and for Grounding and Bounding
- Unlike other brands our system can be dismantled and re-used
- Cable dimension marked on block
- No adaptation of standard blocks needed

Correct and safe installations
To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.
