UNEX RR99K2W4X8-A Gravity Rack Knuckled Span-Track Wheel bed Add-On 48"W x 96"D x 84"H W/4 Levels

The UNEX RR99K2W4X8-A Gravity Rack Add-On is a 4‑level wheel-bed rack extension designed to expand your existing roller rack system. Built to support carton flow, this add‑on provides a 48" wide by 96" deep footprint and stands 84" tall, delivering organized, gravity-fed storage for floor-ready cases and totes without occupying pallet positions. The unit is constructed from steel and ships as a single package, requiring assembly to integrate with compatible UNEX Gravity Flow Roller Rack components.

With four levels, each rated to handle substantial loads, the wheel-bed configuration supports smooth, guided movement of cartons along the track. The specified 2" axle center and 2000 lb shelf capacity per level indicate a sturdy, engineered solution for distributing product flow across the rack while maintaining stable staging. The add-on is color‑coded blue and is intended to remain stationary, aligning with common warehouse layouts where modular, knock‑down frames minimize freight costs and ease of reconfiguration. The total system weight and footprint should be considered for floor loading and space planning in distribution and manufacturing environments.

Practical considerations include ensuring compatibility with existing UNEX gravity flow rails and proper assembly to maintain level alignment and flow efficiency. This item is not eligible for return or exchange; for accurate shipping costs, it should be added to a formal quote. Overall, the RR99K2W4X8-A adds capacity and flow control to carton handling operations that require fast, reliable turnover of cases in a fixed, four‑level configuration.
