Cable and pipe transits primarily used for applications in hazardous maritime and offshore environments where the possibility of fire, explosions, water penetration or other danger poses a real threat, and where the rapid access to emergency services is limited or non-existent.

RGSK

For installing at a distance

RGSK transit are recommended if pooling of water on the transit face makes it necessary to install packing blocks at a certain distance from the deck or bulkhead.

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.

RGSK is an extended, standard RGS transit, with machined grooves for stayplates and compression plates. The material is 10 mm (0.39”) thick on the ends and 12 mm (0.47”) thick on the sides.

RGSK frames are recommended if pooling of water on the transit face makes it necessary to install packing blocks at a certain distance from the deck or bulkhead. The frame is 120 mm (4.72”) deep (as opposed to 60 mm (2.36”) on a RGS) and of standard internal width 120 mm (4.72”).

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.

 

For size and weight please see tables in the MCT Online Catalogue:

MCT Catalogue

The system consists of a frame, rubber blocks and a compression unit. The frame is welded or 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.
