Part of the MCT Brattberg cable and pipe transit system, AddBlocks are supplied with inserts to fit five different cable of pipe diameters. The inserts are of varying thickness - simply choose the correct one for your cable size and fit into the AddBlock creating a seal as secure and tight as using a standard block.
The inserts are fitting with a locating ridge that fits exactly into furrows in the main block, stopping the block from "telescoping" and holding the cable/pipe secure.
Manufactured from Lycron (a synthetic polymer) they have been developed to withstand fire, explosions, temperature variation, ageing, radiation and rodents.
MCT Blocks are self extinguishing and do not release corrosive gases when subjected to fire. They are self-lubricating to facilitate installation.
AddBlocks can be used with standard blocks in a transit.
