The QueuePro 300 is designed for creating large queue systems where its 16? belt halves the number of barriers that are needed with the industry standard 7.5? belt. Fewer barriers lowers total purchase cost and reduces the labor required to set up and take down queue systems. The belt mechanism is housed inside the 3? diameter post giving the QueuePro 300 a sleek, elegant look and despite the long span the belt won?t sag. 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.
