Traveler curtain

Traveler curtains remain at a fixed elevation and open and close horizontally, break up and meet in the middle, and consequently require a minimum of fly space.

The curtains are typically made of velvet[1] and decorated with a series of vertical box pleats along the top edge.

Each trim chain hangs from a wheeled assembly called a roller or carrier that is supported by and rolls along the inside of a horizontal metal channel or track.

Pulling on the other rope segment causes each master carrier to travel toward center stage along with the curtain's moving edge.

[4] When operated in this manner, they require at least as much fly space above them as the height of the curtain itself, but they allow a production to reveal or conceal the stage extremely quickly.
