Retractable belt barriers are the workhorses of crowd control and can be used just about everywhere. Like other kind of stanchions and barriers, these barriers consist of a circular base and a post, but at the top, instead of having attachments for rope or chain, you get a self-contained cassette with a polyester belt spooled within. This belt can be extended and attached to points on adjacent stanchions for a full queue and crowd control management system set-up. There are many online websites that provide such kind of posts such as http://alphacrowdcontrol.com/Plastic-Expandable-Gate-PEG.php, etc.
Retractable belt barrier is a more versatile option than traditional metal posts. The belt barriers allow you to customize the length between stanchions easily, since ant amount of belt can be deployed. You can easily retract the belt to allow access when required without making any changes to the overall configuration. Though they are usually made of metal, there are plastic retractable belt barriers that are used in outdoor applications.
These kinds of posts are an excellent option anywhere you desire a reliable, durable and versatile crowd control solution for banks, warehouses, restaurants, airports, bars, retail stores, lobbies, offices, movie theatres – basically anywhere you need some solid crowd control set-up. They may not be as pretty as classic posts, or as light and weather resistant as plastic posts, but they will get the job done.
