E-RGSFBO
E-RGSFBO 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 E-systems
- Protects against electrical and magnetic interference (EMI), “bugging”, electronic sabotage (SEMP) and static electricity (ESD).
- Assists cable management.
- Integral earthing between cables and wall screen.
- Also seals the penetration against the passage of fire, water, gas, sound and environmental hazards.
- Special E-Series for Grounding and Bounding
- System can be dismantled and re-used.
Technical specifications
E-RGSFBO is a standard E-RGS transit with a flange that allows the frame to be welded into a hole which is slightly larger than the frame.
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.
E-RGSFBO can also be installed in multiple frames.
E-RGSFB transits are supplied in kits, complete with drilled holes, bolts, nuts, washers and a gasket or sealing compound. The flange is 60x10mm. (2.36”x0.39”).
Standard frames come in four sizes: 2, 4, 6 and 8. They are all the same width. Height differences are shown below. The material is 10 mm thick.
The EMC secret is a tempered metal sheet which systematically stops electrical current from passing along the cable screening through the seal and successfully function as an extended wall screen.
- All dimensions are exactly the same for the standard MCT Brattberg components.
- All Insert Blocks are marked with yellow marking (see instructions).

Instructions
EMC
- All dimensions are exactly the same for the standard MCT Brattberg components.
- All Insert Blocks are marked with yellow marking (see instructions).
Grounding and Bonding
- For grounding & bonding applications standard presswedge or endpacking is sufficient.
- Series RGS, RGB, RGG, and E-RGP These products are primarily intended for grounding and bonding of communication, instrument, power, braid or wire armored cables and copper pipes, up to max. 1 AWG.
- Plugs and Wraps are only for use in Grounding and Bonding applications, not EMC.
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.
Bolting
- The Stainless steel bolts A4 M12 recommended torque value is 75 Nm.
