Hammond 3U Adjustable 2-Post Vented Dual-Channel Shelf | 24″ Depth

The Hammond 3U Adjustable 2-Post Vented Dual-Channel Shelf | 24″ Depth (DNRMV Series) is a heavy-duty rack shelf engineered for telecom and network environments requiring strong support, airflow, and flexible mounting. Designed specifically for 2-post racks, this shelf provides a stable platform for non-rackmount equipment, battery systems, and deep chassis components.

Constructed from heavy-gauge steel, this dual-channel shelf supports up to ~300 lbs, making it ideal for heavier equipment such as UPS units, power supplies, and telecom hardware. The vented design promotes airflow, helping prevent heat buildup and extending equipment lifespan—especially in dense rack environments.

Its adjustable side brackets allow mounting to either 3″ or 8″ channel rack widths, providing flexibility across various 2-post rack configurations. The dual-channel structure also enables front and rear access to equipment, making installation and maintenance significantly easier.
