Abstract
A building entryway assembly has the appearance of a fixed sidelight and the functionality of a hinged sidelight. The building entryway assembly includes a hinged main entryway door and at least one hinged sidelight having a lock side that meets the lock side of the main door, such that the sidelight can be selectively opened in addition to the main door when needed to expand the entryway access area. An astragal is fixed to an outer surface of the sidelight at its lock side, and the door threshold includes an astragal boot which aligns with the sidelight astragal when the sidelight is in its closed position. When so aligned, the astragal and astragal boot have the appearance of a fixed astragal extending from the threshold to the header, such that the sidelight appears to be a standard fixed unit with its hinged functionality disguised.
