The UNEX RR99K2W4X6-A Gravity Rack Knuckled Span-Track Wheel bed Add-On provides a stationary, four-level extension for a roller rack system, designed to support carton flow in distribution, manufacturing, and retail environments where pallet storage above the rack is not required. This add-on measures 48 inches wide, 72 inches deep, and 84 inches high, and features a wheel bed track configuration to facilitate gravity-fed movement of cartons along each level. Constructed from steel, it pairs with the existing rack framework to create an efficient, space-conscious storage solution with a total of four levels and a per-shelf capacity rated to handle substantial loads as part of a gravity flow system. The design emphasizes compatibility with pre-engineered roller rack structures and offers a knock-down, easier-to-assemble footprint that helps minimize freight costs and potential handling damage during installation.
Key construction and distinguishing features include the knuckled span-track wheel bed geometry, which supports smooth carton transition across levels, and a 2-inch axle center that governs track alignment within a robust steel framework. The unit ships as a single add-on component and requires assembly, reflecting its role as a modular expansion to existing roller rack lines. Weight and capacity characteristics—1650 pounds for the unit and 12000 pounds overall shelf capability—inform loading plans and how many cartons can be staged per level, while the blue finish aids visibility and identification within busy facilities. The product is designed for stationary deployment, reinforcing a stable cart flow path once installed.
This add-on is compatible with UNEX Gravity Flow Roller Rack systems and is sold under the manufacturer part number RR99K2W4X6-A. When planning installation, consider site-specific factors such as available bay width, existing rack configuration, and the need for precise alignment of knuckled-track components. Packaging is listed as Each, and the item is not eligible for return or exchange per the manufacturer’s note. For accurate shipping costs, add to a quote as requested by the supplier.
