Zilok.com has some line stanchions for rent. That's the only place I've found.
www.StanchionWholesaler.com has 5' Velvet Ropes with Metal Snap Ends.
Those barriers are called traditional velvet ropes and posts. Some call the posts stanchions, but it's basically the same thing. Stanchions are just more elegant. You don't really see the velvet ropes in film theaters unless it's a premiere night for a movie or a special event. The velvet ropes carry a certain aura of class and importance compared to the retractable belts more commonly seen.

A velvet rope is a line divider, but a very classy one. You will find these things in places like the opera, theater, VIP events like the charity and awards events. The material complements the formal attire of the guests while at the same time, keeping riff raffs and media and press people a good distance away from the VIPs. It protects everyone from what could turn into a chaotic mob scene especially if you have celebrities walking down the red carpet.

Those red cords are called velvet ropes. They are soft and look like vellum, but stiffer. Velvet can come in different colors, and they're not restricted to red. However, since red is the most popular, that's what you see most of the time. Occasionally, you might spot a blue, pink, or even black velvet rope, and it does create a different impact. I guess it depends on what movie is showing at the time. Source: crowdcontroldirect.com/
