X2P - Double Bolt
The X2P Double Bolt is a patented security system that locks both sides of the headband, creating a doubly redundant protection mechanism. This ensures that the design effectively resists attempts to pull, undermine or stretch the lock.
Z-Cylinder
The Z-Cylinder is an advanced protection system against mechanical tampering such as sawing, drilling or undermining. The cylinder design increases the lock's resistance to tampering attempts and provides a higher level of security.
