E-RGSR is used in decks and bulkheads which are subjected to high degrees of stress. The additional, rounded ends prevent stress cracking.

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-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.


The E-RGSR is welded into an accurately pre-cut hole in the deck or bulkhead. As with all our transits, E-RGSK is produced in steel, stainless steel, or aluminium.

The radius of the ends is 70 mm (2.76”).

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-RGSR can be used in multiple frames.
For weight charts and installation details, singularly or in multiple frames, contact MCT Brattberg.

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).

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.
MCT Brattberg E-series Installation

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.
