This classic steel stanchion is perfect for safely controlling crowds, directing the flow of foot traffic, or protecting a closed area for construction or cleaning. Unlike other stanchions that begin to wobble over time and require endless repair, these Premium Stanchions will never lean or require maintenance due to their patented Sta-Straight Technology. Designed with four points of contact under continuous tension plus a high-strength compression collar, this spring-tension system keeps the post upright even after extended use. This stanchion also features innovative QuikSecure 5-second setup and tear down that requires no tools for easy twist-and-lock assembly. These receptacles feature a spring safety locking button to keep the belt securely fastened to the post and prevent accidental belt retraction. The base of the Premium Stanchion is made with durable, scratch-resistant high density polyethylene and filled with Duracast, a very high strength concrete.
