Attachment 12 - Photo 03 - Corridor door threshold.JPG

This is a photograph of a door frame and threshold assembly. The image shows a metal-framed door with a white/cream colored frame mounted in a concrete floor. The door features a horizontal aluminum or metal threshold strip at the base, with visible fastening hardware (screws or rivets) along the frame edges. The threshold appears to be designed to provide a seal or transition between the interior floor and the door opening. The concrete floor shows typical wear patterns, and the door frame exhibits some weathering or discoloration on its panels. The assembly demonstrates standard commercial or industrial door installation details, including the frame-to-floor interface and fastening methodology.
