MCT Brattberg is the inventor of the Multi Cable Transit seal. World leader in the design, development and manufacture of Multi Cable and Pipe transits. It has evolved to become stronger over the years in response to meeting the ever tougher demands on product quality and certification.The round RGP frame was introduced in the 1970s. At first it was designed for core-drilled holes in concrete. Today it is even installed in the decks and bulkheads of ships.Lycron rubber for our insert blocks was introduced in 1986. The same year saw the launch of the composite compression plate with integrated compression bolt. Pre-lubricated blocks, a long awaited feature that saves a great deal of time during installation, arrived in 1994.In 1997 we introduced AddBlock, the universal block, which soon became a success. In certain markets today AddBlock dominates. U-blocks and Plugs arrived in 1999. These together with AddBlocks provide cable and pipe transits with increased flexibility for solving problems in the best and easiest way.2017, MCT Brattberg introduced the new Handiblock. This module compliments our existing system. It gives you greater flexibility without the doubt!Today, the company is a modern industrial business with the MCT Brattberg System as main product. An extensive global dealer network ensures the product's availability in most markets. Exports from Sweden constitute roughly 95% of sales.
