FAB 2000BDNsThis is the current top of the line lock manufactured by FAB. It is a grade 4 cylinder, containing fair amount of anti-drill protection, anti-bump, anti-pick and other protections. It features up to three "sliders", that engage with the key spine, however my lock, and locks I've seen disassembled so far have only two slider slots used. Not sure if the third position is used in some masterkeying schemes, or why it is not being used.
The pins are quite standard - RBC pins in chambers 1 and 5, single spool in chamber 2 and the rest are standard (although chamber 3 and 4 drivers are made of steel).
The sliders are somewhat different compared to likes of Yale Superior or EVVA EPS - their movement is not translational, but circular. They engage with the key spine and as mentioned earlier, only two chambers are occupied. Other interesting thing is, that the first slider doesn't need to be touched at all, while the other has a small rise before the gate and when set, it counter-rotates the core. Another thing is, that it seems that there is not much space for more gates - might be, that there are only two slider variants available.
The core is quite packed - there are lots of steel inserts providing the anti-drill protection, there are the slider grooves and also there is a slot for construction keying (they offer the 2in1 option). One thing to watch for is the empty spring slot for the unused slider - when gutting, if the driver gets there, you are in trouble.
Pickingwise, the keyway is not particularly bad, although deeper hook helps; the only problem was, that the spool in chamber 2 didn't fall into a classical false set, but it hanged on the sidebar. After all other pins were set, I tried to set it and it dropped me on the sidebar. The sliders proved to be pickable using the diamond; the only problem was to position the pick correctly. Setting the second slider caused relatively pronounced counter-rotation and tends to drop some pins in the process.
When the lock is picked, there is a trap in the form of the second sidebar groove - after 180 degrees of rotation the sliders might engage and have to be picked again. Interestingly enough, that doesn't cause much problems with lock disassembly, provided you have pinning shoe with a flat tongue. Thanks to the fact, that the sidebar grooves go all the way to the front of the bible, the core can be removed even with the engaged sidebar.
Speaking of the sidebar - it is interesting, that the sidebar groove is not protected against drilling; if you drill to the sidebar groove, you might be able to pull out the sidebar altogether, leaving only 5 pins to mess with (although picking it might be less time consuming)...
