The sliding aluminum door lock features two reinforced aluminum profiles, each secured with five screws. Each profile locks with two pins, one from the top and one from the bottom, ensuring that the resistance of the screws is evenly distributed. This arrangement achieves maximum anti-burglary security for every type of opening frame, such as single leaf, double leaf, aluminum, iron, wood, or PVC. Ideal for intermediate doors, it focuses on safety while staying at home.
