Msnufacturer of kitchen cabinets with hardware labelled "JX" ?

I am trying to track down the manufacturer of the kitchen cabinets in our condo. There is no label on them anywhere, except the metal rails of the kitchen drawers are inscribed “JX”. Does anyone know whether that indicates who made the cabinets?

I am also going to try to track down who installed the kitchen. But in the meantime, if anyone knows what “JX” signifies, that would be helpful! Thanks in advance.
