A fenestration opening is provided with opposing receptors on opposite sides of the fenestration opening. Each of the receptors is configured to capture and opposing end of a glazed panel with a capture feature or features on each receptor that hold the respective end of the glazed panel from moving laterally, in or out of the fenestration opening. The glazed panel is installed by angling the glazed panel with respect to the fenestration opening and inserting one end of the glazed panel into engagement with one of the receptors, then moving the opposite end of the glazed panel so that the panel is aligned between the receptors, and then moving the panel so that the opposite end of the receptor is captured by the opposite receptor.
