Overview
RGG-O
- Type approved cable transit for buildings
- Can be casted in concrete
- Assists cable management
- Seals the penetration against the passage of fire, water, gas, sound and environmental hazards
- Unlike other brands our system can be dismantled and re-used
- Marked cable designation on blocks for increased safety
- No adaptation of standard blocks needed
RGG-O transit type can be bolted onto concrete, plaster board wall or casted into a concrete wall or floor to protect against flooding, water and ingress.
The transit is made of two angle bars 60x6 and two gables in galvanized mild steel.
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.
Can be installed in horizontal combinations.
Please see information drawings for detailed data.
RGG-O have removable ends which enables installation where cables already have been pulled.

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.
Designation (starting at bottom):
Frame type 6x4
VERTICAL MULTIPLE FRAMES
Vertical multiple frames are described by listing the bottom frame type and size + the next frame type and size.
Designation (starting at bottom):
(frame type) 6+6+4 and (frame type) 6+4+2
VERTICAL AND HORIZONTAL MULTIPLE FRAMES
List the entire vertical frames x the desired number of horizontal repetitions.
Designation (starting at bottom):
(frame type) 6+4+2x4
NOTE: All multiple frame designations must be preceded by the frame type.
