High-Efficiency Meets Heavy-Duty in Dyna-Flo HD

The HD stands for heavy-duty – Dyna-Flo HD is Mallard’s strongest, most durable carton flow racking. As you can see in our 3D animated video, product slotting and reprofiling is easy with the full-width wheel bed design of Dyna-Flo HD which accommodates cartons of different dimensions on each shelf level. Easy to install lane guides and dividers are quickly added or relocated to adjust for new carton sizes and to assist in faster SKU identification and therefore faster pick rates.

The ease of use, flexibility and durability of Dyna-Flo HD carton flow makes it a common application in retail, food, beverage, manufacturing and e-commerce distribution centers.
