Basic to the procedure are three different elements used in the Metalock procedure. Matching keys (Metalocks) made of special alloys
Another element is screws or pins (Metalace) which are used to close cracks against leakage.
Screws are screwed into the drilled holes, next to each other along the line of the crack.
The third element is the plates (Masterlocks) with inserted high-load inlets.
The board is held using screws that are placed so that one half is on the base material and the other on the board.
