Heavy-duty Network & Server Racks / WN428
42U 800mm Depth Rack-mount Server Cabinet
A standard-height 42U Claytek WN cabinet at 800 mm depth — full data-center RU count in a shallow footprint.
Product Overview
What the WN428 is built for.
WN428 is the 42U × 800 mm Claytek WN enclosed cabinet, measuring 23.50" × 82.50" × 31.50" (596.9 × 2,095.5 × 800.1 mm). Supported chassis depth is 27.5" and under (internal 26.5" max). Use it when you need a conventional 42U rack height but the aisle or room cannot take 1000 mm or 1200 mm cabinets. Same WN locks, double rear doors, and 120 mm top fans as the 15U–36U 800 mm models. Sliding-rail option: WN428-EX. Optional WA-PLATE-HD for higher loading.
