The QueuePro Twin 250's lower belt restricts pedestrians from ducking under the belt, helps keep children in line and provides guidance for the visually impaired using a cane. The bottom belt makes this stanchion ADA (Americans with Disabilities Act) compliant. This post features a unique two piece post construction which allows the lower belt mechanism to be easily replaced in the field. QueuePro stanchions offer the durability of steel construction and a heavy duty cast iron base. The long service life of these stanchions makes them ideal, ideal for high traffic areas or where the stanchions are moved frequently. All QueuePro stanchion models feature a braking system for slow, safe belt retraction and a locking belt end to prevent accidental release. A full circumference floor protector to prevent floor damage is standard. QueuePros?s 4-way connectivity allows belts from three other stanchions to be connected in line or at right angles so complex queue systems can be created.
