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

The Hammond 3U Adjustable 2-Post Solid Dual-Channel Shelf | 24″ Depth (DNRMU Series) is a heavy-duty rack shelf designed for telecom and network environments where maximum strength and equipment support are required. Built specifically for 2-post racks, this shelf provides a stable, high-capacity platform for mounting non-rackmount equipment, batteries, and deep chassis hardware.

Constructed from heavy-gauge steel with reinforced front and rear lips, this dual-channel shelf supports up to ~300 lbs, making it ideal for heavier equipment such as UPS systems, power supplies, and telecom gear. Unlike vented models, the solid surface design provides full equipment support, preventing smaller devices or uneven loads from sagging or shifting.

The dual-channel design allows front and rear access to equipment, improving installation flexibility and simplifying maintenance in relay rack environments. Adjustable mounting brackets support both 3″ and 8″ channel racks, ensuring compatibility across a wide range of 2-post configurations.
