E-RGS
E-RGS cable and pipe transit are welded in high-risk maritime and offshore environments to minimize danger by preventing the spread of fire, water, gas, chemicals, EMI and other hazards substances.
The system consists of a frame, rubber blocks and a compression unit.
The frame is welded 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-series system
- 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.
- E-Series approved for Grounding and Bounding
- System can be dismantled and re-used.
Overview
E-RGS has a standard internal width of 120 mm (4.72”) and is 60 mm (2.36”) deep.
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.
They may be used in both vertical and/or horizontal multiple frames. The E-RGS is welded into an accurately pre-cut hole in the deck or bulkhead. As with all our frames, E-RGS is produced in steel, stainless steel, or aluminium.
For installations where cables are already in place, specify E-RGSO, which has a removable end.
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.

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.
