OnGuard’s patented X4P Quattro Bolt secures both sides of the shackle, creating a double-redundant system resistant to pulling, jacking, prying, and twisting. It secures the shackle to the crossbar in four places for maximum strength, with hardened steel throughout to resist all attacks. The shackle’s dual-end securing requires defeating both sides to open, and round profiles with smooth edges eliminate leverage points.
Cable locks with X2P Dual Lock Down mechanisms secure cable to lock head in two places for high pull and pry resistance.
Locks equipped with Z-Cylinder systems come standard with 5 laser-cut keys. The advanced technology of the Z-Cylinder significantly enhances the security level of our locks, making them extremely difficult for unauthorized duplication.
No more struggling with combinations in the dark. Our Doberman and Terrier Combo Glo locks are equipped with backlit tumblers for easy use in low-light conditions.
