For pick modules that receive cases, cartons, and totes another pragmatic kind of flow rack is needed to deliver product to the pick zone. Carton flow rack slopes down to the pick zone so that gravity forces product to the pick face. There are different varieties of carton flow rack to suit different capacities and applications.

• Light duty carton flow rack: polyethylene rollers with molded plastic axles will get the job done, but larger rollers and galvanized steel axles can be used for heavier loads or usage.
• Medium dut carton flow rack: full-width aluminum rollers support larger packages for delivery to the pick zone.
• Heavy duty staggered wheel skatebeds: staggered skatewheel beds can be trusted to support heavy loads and endure significant stress, and such components can easily be configured into existing rack.
