Each exhibition opens on the First Friday of each month, and is marked by a reception scheduled for 5-8 PM.  Exhibits typically run 21 days, and are closed for a week or so for changeover.  Except on First Fridays, exhibits are open to the public whenever the Roebling Lofts leasing office is open: daily, 9 AM – 5 PM.  Front doors are locked, but you can buzz the leasing office from the Clark Street entrance for admittance.
