Do the NEMA 4X non-metallic enclosures for enclosed control units come with hubs ?

No,  the NEMA 4X non-metallic enclosures do not come with hubs. The enclosure will need to be cut and hubs sourced in the field based on conduits size .  The metallic NEMA 4X enclosures do come with hubs as shown in the catalog and drawings.
