The UNEX RR99S2R4X6-A Gravity Flow Roller Rack with Span Track Add-On is a pre-engineered steel storage solution designed to support carton flow in order-picking environments. Sized as 48 inches wide, 72 inches deep, and 84 inches high, this rack add-on brings four levels of capacity to an existing system, enabling selective, first-in, first-out carton handling with three 12-inch wide span-tracks per level for a total of three lanes per level. The roller-track configuration supports smooth gravity flow, helping operators move cartons from pick face toward the shipping area without manual re-handling. The unit is finished in blue and is built for stationary use, requiring assembly during installation, with a notable weight of 818 pounds and a total shelf capacity of 2,000 pounds per level, up to a wider rack system capacity of 12,000 pounds.
Construction and distinguishing features focus on robust, pre-engineered design. The RR99S2R4X6-A is fabricated from steel and configured as a rack add-on, maximizing space utilization in facilities that do not require pallet storage above the rack. The axle center spacing is 2 inches, which contributes to stable roller guidance and load distribution across each level. With four levels and dedicated Span Track lanes, this unit is intended to be part of a larger carton-flow setup that supports medium-duty warehouse operations, distribution centers, and retail fulfillment floors where carton flow and flow-through picking are priorities.
Practical considerations include its assembly requirement and its status as stationary equipment, suitable for installations where mobility is not needed. Each add-on ships as an individual package and is designed to integrate with compatible UNEX rack systems to extend carton-flow capacity. While this description notes the key dimensions, weight, and load characteristics, confirm compatibility with your existing rack configuration and total system capacity prior to purchase to ensure safe, compliant operation in your facility.
