In addition to the various blocks and windows, MCT Brattberg also offers a selection of tools and products that can be used during assembly. Using the accessories from MCT Brattberg, the installation of a penetration can not only be simplified, but also carried out more accurately and safely. Examples of MCT Brattberg accessories are the Packing Tool, with which the existing blocks can be temporarily pressed during the filling of a window, and the Casting Forms and Casting Modules, with which the correct cut-out can be realized prior to placing a passage window in a new concrete wall, by applying the Casting Forms to the desired positions already prior to pouring the concrete.
