Hammond DNRMU2324BK1 3U 24in Deep Solid Rack Shelf, 275 lb Load

The DNRMU2324BK1 is a 3U variable-depth rack mounting shelf with a solid (unvented) deck, sized for 23 inch rack rails and offering 24.00 in (610 mm) of usable depth. It is intended for IT, AV and industrial users who need a deep, rigid platform for non-rack-mount equipment such as monitors, amplifiers, converters, test gear or tools inside an open two-post rack.

Construction is heavy-duty 16 gauge mild steel, finished in textured RAL9005 black powder coat that complies with the Greenguard guidelines for indoor air quality. The front and rear lips are folded for extra strength and double as equipment retainers, helping keep gear from sliding off the shelf. The drawing for DNRMU2324BK1 lists a maximum weight load capacity of 275 lb, while the DNRM series is load rated to 300 lbs (136 kg).

Mounting dimensions are 5.25 in (133 mm) high by 23.00 in (584 mm) wide by 24.00 in (610 mm) deep, occupying 3U of rack space. The assembly consists of the DNRM shelf with four mounting brackets, and mounting hardware is included for both 10-32 and 12-24 rails (eight 10-32 x 1/2 screws and eight 10-32 KEP nuts). Bracket slots and eight 0.25 x 0.38 in mounting slots allow the depth position to be set as the installation requires.

• Designed for use with heavy-duty DNRR and DRZ4 double-tapped two-post racks, or any two-post rack.
• Shipping weight 18 lbs (8.16 kg).

DNRMU2324BK1 is manufactured in North America, is RoHS and REACH compliant, USMCA compliant, and TAA-compliant for federal GSA schedule purchases within the USA. Note that the DNRM product line will be discontinued on October 01, 2026, after which it is available while supplies last, with no returns possible after the discontinuation date; the suggested replacement is the BRS Series.
