Very high resistance
Homeowners can protect themselves against violent break-in attempts with this VdS-certified security bolt. Small bar, big impact: With the security bolt, you can reliably secure your wooden, metal, and plastic doors against intruders. The bolt is installed across the entire width of a door measuring between 73.5 and 103 centimeters. It firmly engages in two locking boxes that are anchored in the masonry. Thanks to its special drive mechanism, the security bolt can be used quietly. Mounting materials and three keys are included in the delivery.
