The 50 is a pin-tumbler lock made by FAB. It has a rating of resistance class 1, which means it is meant to be used for temporarily locking objects without providing much security.

Principles of operation

See also: Pin-Tumbler (Principles of Operation)

The lock contains five pin stacks, with two chambers containing standard drivers, and three chambers contain spools. These spools, along with usually quite aggressive bitting do provide some basic anti-picking protection. The profile used (R14) is not paracentric, and there is no anti-drill or anti-bumping protection.

Disassembly instructions

To disassemble a double euro cylinder, use of a pinning shoe is the preferred method.

Other possibility is to use a segmented follower, but that requires that both cores are pulled out a bit to allow a cam removal. Then a core should be rotated to approximately 4:30 or 7:30 o'clock position (135 degrees either clockwise or anti-clockwise) to prevent driver entering a gaps for the cam clutch. Then a segmented follower can be used to remove the core.


The FAB 50 is vulnerable to one or more of the following:
