'''FAB 3* Profi''' and '''FAB 4''' are two [[pin-tumbler]] locks from [[Fab\|FAB]]. FAB 3* Profi belongs to a resistance class 3, FAB 4**** belongs to resistance class 4. These locks differ significantly from previous FAB products; both are six pin locks but they have new designs for key shoulder, shoulder stop, pins, cam clutch, and other components.

'''FAB 3*** Profi''' and '''FAB 4****''' are two new locks from [[Fab|FAB]]; FAB 3*** Profi belongs to a resistance class 3, FAB 4**** belongs to resistance class 4. These locks differ quite significantly from the previous FAB's products - both of them are six pin locks, they have a new key shoulder and shoulder stop, new pins, different cam clutch and more...
