The DNRMA1916BK1 is a 3U adjustable cantilever rack shelf built for standard 19-inch rack systems, giving IT, AV, telecom and control-system installers a solid platform for equipment that will not mount directly to rack rails. It is designed primarily for open relay racks, while also supporting panel-mounted rack applications, and is rated for loads up to 275 lb (125 kg).
Construction is 14-gauge mild steel with a black textured powder coat finish that is GREENGUARD, TSCA and RoHS compliant. The shelf ships knocked down for easier handling and shipping protection, and comprises the DNRMA 1916 shelf panel, left and right side brackets, and six 10-32 KEP nuts. Mounting hardware is included for both 10-32 and 12-24 rails.
Mounting width is 19.00 in (483 mm) across an EIA 19-inch rack, mounting height is 5.25 in (133 mm) occupying 3U, and the overall shelf depth is 16.00 in (406 mm) with an inside width of 17.47 in (444 mm). Four 0.25 x 0.44 in mounting slots are provided for rail attachment.
What sets this shelf apart is its movable side brackets: they can be mounted inside or outside the rack at four different depths, so DNRMA1916BK1 can be positioned to match varying equipment depths, improve load distribution and reduce stress on the rack rails.
- 3U, 19 in mounting width, 16 in overall depth
- 275 lb (125 kg) maximum weight
- Four-position adjustable side brackets
The part is TAA-compliant and manufactured in North America in an ISO 9001 certified facility, and is USMCA, RoHS and REACH compliant.
