The flexible panel defines an upper portion having a first width and a lower portion having a second width less than the first width. At least one pass door frame is hingedly securable proximate a lateral side of the opening for movement between a first position, in which the pass door frame extends in a substantially transverse direction relative to the opening and a second position, in which the pass door frame is substantially aligned with the at least one sidewall.
