The most commonly used lock for desks are pedestal locks which have a rotating peg mechanism. The peg or actuator cam to give it it's technical term, lifts and lowers the locking bar, which in turn locks and unlocks the set of pedestal drawers. they come in a range of types including single flanged, double flanged, snap in fix and horseshoe clip. Depending on the build of the furniture you can either have a horizontal or vertical orientation of the lock. This is an important detail when ordering replacement locks to ensure that the actuator cam is correctly positioned to activate the locking bar. The locking bar is built into the frame and runs the vertical length of the furniture.Comments
Some pedestal locks have an anti-tilt function meaning that the peg of the lock is design to resist entry more so than non anti-tilt versions, the anti-tilt is more commonly found in newer versions of this lock.
