Hammond DNRMA2316BK1 3U 23-Inch Adjustable Shelf, 275 lb Capacity

The DNRMA2316BK1 is a 3U adjustable rack shelf with a 23 in mounting width and a 16 in shelf depth, intended for open relay racks and panel-mounted rack applications. It suits IT, network, telecom and industrial control installations where servers, chassis or non-rackmount equipment of varying depth need solid, well-distributed support.

Construction is 14-gauge steel with a black textured powder coat finish that is GREENGUARD, TSCA and RoHS compliant. The shelf carries a maximum load rating of 275 lb (125 kg), making it suitable for heavy chassis and equipment that cannot be rail-mounted. Material is mild steel, and the part is REACH and RoHS compliant, USMCA compliant and TAA-compliant, manufactured in North America within an ISO 9001 certified facility.

Movable left and right side brackets let the shelf be mounted inside or outside the rack at four different depths, so one shelf can adapt to a mix of equipment sizes while spreading load across the rack mounting points and reducing stress on the rails. The front panel measures 23.00 in (584 mm) wide with 0.25 x 0.44 in mounting slots on 22.35 in (568 mm) centres, and the shelf platform is 16.00 in (406 mm) deep.

DNRMA2316BK1 ships knocked down for easier handling and shipping protection, and includes the two side brackets plus six 8-32 x 1/2 in screws and six 8-32 KEP nuts for assembly. Mounting hardware is included for both 10-32 and 12-24 rack rails. Shipping weight is 12.5 lbs (5.67 kg).
