- An architectural term applied to the upright iron bars in windows that pass through the eyes of the saddle bars or horizontal irons to steady the leadlight. (The French call the latter traverses, the stanchions montants, and the whole arrangement armature. Stanchions frequently finish with ornamental heads forged out of the iron.)
- An architectural term applied to metal supporting members of lighting mounted from a lower elevation. This includes:
