The DNRR70HDW is a 40U welded 2-post open frame rack built for high-capacity IT, telecom, and data center installations. It is part of the DNRRHDW heavy-duty series, a 19" EIA compliant relay rack platform intended for network, telecom, and data center equipment that needs more support than a standard welded rack provides.
Construction is 10-gauge welded steel (mild steel) finished in RAL9005 Black powder coat, with the series finish described as GREENGUARD, TSCA, and RoHS compliant. The welded assembly is UL2416 rated to 1500 lb and UL listed under file number E474597, and the series is seismic rated to 400 lb (181.44 kg) dynamic load (Ip = 1.5) in accordance with IBC, CBC, NBC, and ASCE standards.
This part number measures 76.13 in x 20 in x 15 in (1,934 mm x 508 mm x 381 mm) as listed, with the drawing showing 20.56 in (522 mm) overall width and 15.00 in (381 mm) depth. Mounting height is 70.00 in (1778 mm) over 40 rack units at 19.00 in (483 mm) mounting width, with a 3.00 in (76 mm) rail depth and a 17.75 in (451 mm) opening between rails.
- Double-tapped 10-32 rails, front and rear flanges, standard EIA spacing with U marks
- Four 0.75 in (19 mm) floor-mounting holes in the base for freestanding installation
- Four 10-32 x 1/2 studs for bonding and grounding
The DNRR70HDW is made in Canada, USMCA compliant and TAA-compliant, and pairs with the RB-VCM40 vertical cable manager. Two racks plus the Four Post Rack Kit (FPRK) convert it to a four-post configuration.
Ideal For
- Data centers and high-density IT environments
- Telecom installations requiring high load capacity
- Infrastructure deployments with heavy or power-dense equipment
- Installations where equipment weight exceeds standard rack capacity
- Regulated environments requiring seismic-rated rack mounting
