Hammond DNRMU23BK1 3U 23-Inch Solid Rack Shelf, 19" Depth

The DNRMU23BK1 is a 3U solid-surface rack shelf sized for 23 inch two-post racks, giving integrators, electricians and facilities teams a flat, load-bearing platform for non-rack-mount equipment. It is part of the DNRM variable-depth rack shelf line and is designed for use with heavy-duty DNRR and DRZ4 double-tapped two-post racks, or any 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 surface. The solid version provides an unbroken platform; a vented version (DNRMV23BK1) is offered in the same size for applications where upward heat movement should not be obstructed.

Mounting dimensions are 5.25 in (133 mm) high by 23.00 in (584 mm) wide with a 19.00 in (483 mm) depth, occupying 3 rack units. The drawing for DNRMU23BK1 shows an overall shelf width of 23.00 in (584 mm), a 19.00 in (483 mm) deep top and eight 0.25 x 0.38 in mounting slots across the front. The shelf ships with four mounting brackets plus 10-32 KEP nuts and 10-32 x 1/2 screws, and mounting hardware is included for both 10-32 and 12-24 rails.
