ESSVE Indu-Prog KarmFix is designed to make installation of windows and doors in walls/structures of wood with Indu-Prog Frame sleeves easier, quicker and safer.

Through using the Indu-Prog Frame sleeves, which are fitted in the frame, Indu-Prog KarmFix ensures that the window/door is in the right position and aligns the Indu-Prog Wood screws or Indu-Prog Concrete screws, which also work in wood.

See installation instructions at the end of this section.
