CHC NewsletterCustom-engineered for space optimization and efficiency, UNEX's SpanTrack is the carton flow solution to improve productivity and accuracy on the pick line. It seamlessly integrates into existing structures, transforming them into high-performance flow rack systems ideal for order picking operations and manufacturing facilities. The first-in, first-out (FIFO) rotation reduces picker strain while allowing you to optimize every inch of warehouse storage space. Featuring full-width roller lanes and universal wheel beds, SpanTrack offers unparalleled versatility for storing products of various sizes and weights.
