Each block consists of two halves which together creates a square shaped 60 mm long sealing insert. Standard insert blocks are divided up in seven sizes, 15, 20, 30, 40, 60, 90 and 120 mm in square.
They are designed to seal cables and pipes with diameters from 3.5 – 110 mm (0.14-4.33”).
Part of the MCT Brattberg cable and pipe transit system, insert blocks are available for cable diameters from 4mm to 100mm.
Manufactured from Lycron (a synthetic polymer) they have been developed to withstand fire, explosions, temperature variation, ageing, radiation and rodents.
