Stanchions and velvet rope

A stanchion (/ˈstænʃən/) is a sturdy upright fixture that provides support for some other object. They are often not a permanent fixture, so that they may be expediently enlisted or removed whenever desired.

Types

• An event management term applied to an upright bar or post that includes retractable belts, velvet ropes, or plastic chains, sometimes in conjunction with wall-mounted barrier devices, and often used for crowd control and engineering people flow.
• 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:
  • The metal inclined member for mounting a streetlight to a telephone or power pole.
  • 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.
• Upright posts inserted into the ground or floor to protect the corner of a wall. These may also be referred to as balusters or bollards.
