RGB & RGG System - For casting or bolting.


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

The frame is casted or bolted to a 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. 

  • OVERVIEW

     

    RGB & RGBO

    RGB frame type is casted into a concrete wall or floor. It is manufactured from a 60x60x6 mm angle bar

    RGBO frames are of the same type as the RGB frames but with one of the ends removable which enables installation where cables already have been pulled.

     

    RGG & RGGO

    RGG  frame type is bolted onto a concrete wall or floor or a plaster board wall. It is manufactured from a 60x60x6 mm angle bar.

    RGGO frames are of the same type as the RGG frames but with one of the ends removable which enables installation where cables already have been pulled.

     

    Insert Blocks

    MCT Brattberg’s insert blocks are manufactured from Lycron, a synthetic polymer that was developed to withstand fire, explosions, temperature variation, ageing, radiation and rodents. The blocks are injection moulded giving precision components to a high degree of accuracy. Standard blocks are available for cable diameters from 3,5 – 110 mm. Other dimensions can be supplied to order.

     

    stayplate

    To be placed between each row of blocks. Stayplates make installation simple, increase stability and anchor blocks within the frame. Stayplates are manufactured in galvanized steel, stainless steel, aluminium and brass.

     

    stg-endpacking

    Installed between compression plate and the top of the frame, completing the seal. Manufactured from Lycron with galvanized mild steel or stainless steel hardware.

     

    compression plate

    Inserted above the top row of blocks. It is equipped with a special telescopic bolt which is tightened to compress the system enabling installation of the STG endpacking. Manufactured from GRP, glassfibre reinforced polyester.

     

    ptg-presswedge

    Used as an alternative to the compression plate and STG Endpacking can also be placed anywhere in the frame. It compresses the system and completing the seal. Manufactured from Lycron with galvanized mild steel or stainless steel hardware.

       

    lubricant

    MCT Brattberg Lubricant consists of pure beef tallow. It is used to improve the system’s water and gas tightness and shall be applied on all Lycron parts sealing surfaces when such demands exist.

  • TECHNICAL SPECIFICATIONS

    RGB & RGG

    The standard frame is made of an angle bar 60x60x6 mm, in mild steel, stainless steel or aluminium. The mild steel frames are supplied with two types of surface finish, primer or galvanized. The internal width is always 120.5 ± 0.5. The standard height varies with the sizes - numbered 2, 4, 6 or 8, which give heights of 100, 159, 218 and 276 respectively. All the frames can be manufactured in combinations.
