When a belt frays, jams, or stops retracting, the rest of the stanchion is usually still in fine shape. Rather than retire a working post from your checkout line or lobby queue, swap in this replacement belt mechanism. The cassette installs in the head of a Beltrac stanchion and restores smooth extension and controlled retraction. Belt lengths of 10 ft or 15 ft cover standard and extended runs, and colors include Black, Blue, Red, Gray, Burgundy, Bronze, Marine Blue, Forest Green, Silver/Black, and more, so you can match your existing posts or refresh the look of the line. Keeping a spare mechanism on hand turns a belt failure into a quick fix instead of a replacement purchase.
