When strength and reliability are the highest priority, choose the DNRRHDW Series from Hammond Manufacturing. Regardless of the application, the DNRRHDW Series includes premium features not found on most other racks designed to support your rack-mount infrastructure.
Product Features
  • Our premium 10-gauge welded steel frame construction is the most robust steel rack on the market.

  • Our tapping process provides EIA-compliant precision threaded rails on both the front and back to ensure flexibility when mounting equipment.
  • Every rack unit includes rack unit dividers to aid in equipment mounting.
  • When connecting multiple racks, numerous holes are provided for mounting power distribution, cable management and other accessories.
  • Bonding is a breeze with two (2) pairs of integrated 10-32 ground studs spaced 5/8" apart. Stud pairs are conveniently located across from each other inside the rail channel. For added convenience, a pair is near the top of the rack, while the other is at the lower side.
