Types

In architecture a stanchion is 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.[2]

Stanchions are also the metal supporting members of lighting mounted from a lower elevation. This includes the metal inclined member for mounting a streetlight to a telephone or power pole, and the dedicated metal vertical support of a self-supporting or bottom-fed streetlight. In this case, the stanchion pole may double as the raceway for the electrical feed to the lighting.

In industrial installations, walkway lighting may be mounted with a stanchion that is secured to a hand-rail. Stanchion lights are typically spaced 50' along walkways, such as conveyor platforms.

Stanchions (balusters or bollards) are also the upright posts inserted into the ground or floor to protect the corner of a wall.

In event management a stanchion is an upright bar or post that includes retractable belts, velvet ropes, or plastic chains, sometimes in conjunction with wall-mounted barrier devices, barricades, and printed signage and often used for crowd control and engineering people flow and construction site safety.

  • In military aircraft, the vertical supports for troop seating temporarily installed in cargo aircraft.
  • On board most buses and trams/subways, vertical supports to provide stability when passengers are standing. They are located throughout most city buses and are connected to seats, floor, roof, etc.
  • The metal head bails in dairy barns that lock the cows in place while they are milked.
  • The two upper members of a suspension bicycle fork that connect to the crown (also called fork legs).
  • In yachting, metal bars that hold the life-lines around a boat's perimeter.
  • In river rafting, metal bars that hold the yokes for oars.
  • As part of ice hockey rink boards, used to hold panes of glass in place. In the industry they are frequently called poles to minimize confusion.
