There are eleven different sizes of E-AddBlock.


Technical specifications


There are eleven different sizes of E-AddBlock. By tearing off the wing-like inserts, which are of varying thickness, and inserting them in the main block it is possible to accommodate 66 different cable and pipe dimensions, from 3.5 mm to 69.5 mm. The inserts are fitted with a locating ridge that fits exactly into furrows in the main block. These stop the block from ”telescoping”. A seal using E-AddBlocks is as secure and tight as one using standard blocks. Both types can be combined in a transit, which makes the MCT Brattberg seal system very flexible. E-AddBlocks are all the same length as standard blocks, 60 mm. The width of standard blocks (measurement, see table) are 20, 30, 40, 60 or 90 mm.

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.
