FortXLocks Thumb Turn Cylinders are constructed in the same way as the Anti Drill cylinders benefiting from an internal thumb (knob) to lock the door. These should now be fitted by law to any new rental property. This feature allows for anyone to get out of building if it were on fire etc, rather than be locked in. They also benefit from 6 Pin security with hardened anti drill facility.
The 1st number is always the thumb turn side
