These new old stock lock sets are were designed for our old style rack drawers. The lock set includes a lock and two keys. The difference between the lock sets for the old style and new style rack drawers is the old style has a bent tang whereas the new style has a straight tang. The other difference is that the keys from the old style don't fit the locks of the new style and vice versa. The old style lock sets are NOT intended for our current rack drawers without modification.
