It seems like the big repair stands get to have all of the fun. They get the work trays, towel holders, and bells and whistles for all of the accessories. Fortunately, with the addition of the Park Tool 106 Work Tray Accessory Collar you can adapt your smaller PCS-9, PCS-1, PCS-4, PCS-4-1, or PCS-4-2 to accommodate the fun and super useful accessories. Simply slide it on to the upright tube and cinch it down and you'll be able to add your a work tray on for easier home maintenance.
