This fire door was manufactured by the Keystone Fire Door Co., Pittsburg, PA, and was salvaged from a General Electric Plant in New Kensington, PA. The stamped logo appears to have no 'H' in Pittsburgh (From 1891 to 1911, the spelling of the city's name was federally recognized as Pittsburg.). The door has a slanted top. The tall end is approximately 97" and the short end is 94". The door measures 44" wide and is 2 5/8" thick. Would look fantastic in a loft apartment!
