Features

  • Ships fully assembled for rapid deployment and rolls into place on heavy-duty pre-installed casters (casters are removable)
  • Front and rear sets of equipment mounting rails adjust in 1/4" increments. Adjustment is quick and convenient. The easy-view depth index ensures consistent rail placement without requiring time-consuming measurements.
  • Toolless accessory mounting rails (2 rails per enclosure) include slots for quick installation of compatible PDUs and vertical cable managers. Mounting slots are arranged in an industry-standard pattern compatible with a wide variety of accessories. Each rail can accommodate two vertical PDUs or cable managers side-by-side (four items per enclosure).
  • Enclosure includes mounting hardware of 50 pieces of M6 cage nuts and 50 pieces of M6 screws
  • Tough textured powder coat finish resists conditions found in non-IT environments such as warehouses
  • Massive front-to-rear ventilation capacity. 65+% open space in door perforation pattern meets or exceeds server manufacturer requirements

  • Weight ratings of 3000 lbs (1360.8 kgs) stationary and 2250 lbs (1020.6 kgs) rolling
