CRAKKER is a combination lock manipulator NOT an auto-dialer. It can quickly defeat common 3 and 4 wheel locks.

CRAKKER will work on any lock where the fence arm rubs against the cam. It can use the left or right contact point. It works on loose and stiff locks provided dial operation is smooth in the contact test area.

CRAKKER does not produce swarf in locks even after extensive testing. Users must know how to find the contact points  and count the wheels in the lock.

CRAKKER does just about everything else.
