historically, a metal strap used to hang a joist from a larger structural beam, sometimes also referred to as a “stirrup iron hanger” due to its resemblance to a riding stirrup; modern versions are engineered metal connections, usually galvanized steel, used to connect joists to steel beams or engineered wood beams
This historic joist hanger came from the South Wing of the Kansas Statehouse.
