Multi-point locks are widely used in modern doors, especially where increased security, stability and burglar resistance are required. They lock the door simultaneously at several points (usually 3, 5 or 7), offering significantly better protection compared to ordinary single-point locks.
Difficult to break even if one point breaks, the rest continue to hold. They press the door tightly against the frame, ensuring less draft and noise. They distribute the pressure along the entire height, the door does not bend or sag.
