A stanchion () is a sturdy upright fixture that provides support for some other object.
Types
In
architecture, stanchions are the upright iron bars in windows that pass through the eyes of the s 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.
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 handrail. Stanchion lights are typically spaced along walkways, such as conveyor belt platforms.
Stanchions ( 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 or connects to retractable belts, velvet ropes, or plastic chains, sometimes in conjunction with wall-mounted barrier devices, , and printed signage
