What we mean by "Double-Locking"
In a conventional disc-lock, the locking-pin is the weakest point. With XENA's double-locking system, body and locking pin act as one piece of metal, making it virtually impossible to remove the lock by wedging, hammering or other method.
..And what it means for thieves
Pictured at right: a XENA XN15 double-locking disc-lock after several minutes of brutal hammer and wedge attack from independent testers at Classe SRA France. Note that XENA's build quality and double-locking pin mean that despite the awesome force applied, the XENA remains locked .
