RGB Ex
These Ex approved cable and pipe transits are used in high-risk land-based Ex e and Ex tb environments to minimize danger by preventing fire, water, gas, chemicals and other hazards substances.
RGB Ex transit is casted into a concrete wall or floor. It is manufactured from a 60x60x6 mm angle bar.
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

Technical specifications
RGB Ex sizes
The standard transit is made of an angle bar 60x60x6 mm, in mild steel, stainless steel or aluminium. The mild steel transits are supplied with two types of surface finish, primer or galvanized.
Standard frames come in eight sizes: 1, 2, 3, 4, 5, 6, 7, and 8.
The internal width can be 60.5 ± 1 (Size 1,3,5,7) or 120.5 ± 1 (2,4,6,8).
Note that there can be limitations in type-approvals & certificates, making certain sizes inapplicable.

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.
For more information, please view following instructions, videos or download manuals as PDFs.
Multiple frames
HORIZONTAL MULTIPLE FRAMES
Horizontal multiple frames are described by listing the frame type and size x the desired number of horizontal openings.
