Key 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
  • Maximum usable internal depth of 37 inches/94 cm (front to rear rail)
  • Weight ratings of 3000 lb stationary and 2250 lb rolling
  • Front door is locking, reversible and removable
  • Rear doors are locking and reversible. Split rear door design reduces clearance requirements for service entry allowing the enclosure to be placed closer to a wall
  • Locking removable side panels are 'half size' to make them smaller and lighter improving ease of installation and servicing. Two side panels per side (4 panels total). Side panels are keyed alike to the front and rear doors.
  • Built in baying tabs allow enclosures to be combined securely in rows. Center-to-center width can be set at 600mm or 24" to match standard data center floor tiles
  • Leveling feet extend to allow enclosure to be positioned on uneven floors. Levelers are removable
  • Compact design allows the enclosure to roll through standard height commercial doorways
  • Convenient grounding system. All components are grounded to the enclosure frame which includes multiple connections for facility ground. Front and rear doors include quick-release ground wires.
  • Open bottom for cable access
  • Top panel has generous cable access holes. Panel can be removed toollessly in seconds without having to disconnect cables first
  • Included stabilizing brackets are used for shipment and can be reattached at the bottom of the enclosure frame on the inside or outside of the rack
  • Meets all enclosure requirements towards PCI DSS (Payment Card Industry Data Security Standard) Compliance
  • Compatible with airflow optimization and cable management accessories

SR42UB 4.8 5 5 5
Perfect Cabinet I needed a cabinet that was slimmer than the majority of standing enclosures. This perfectly fit the bill. It was easy to move since it had wheels, once in place, I set casters in place. The cabinet is sturdy and now houses my servers. August 22, 2013
Decent rack for the price. Feels very sturdy, not flimsy or cheap like some light weight cabinets that seems like they'll cave in. Pre-assembled and a good overall unit for the money. April 3, 2013
This is a great rack. We got one to replace an old 24U rack that was pretty beat up and starting to show it's age. This rack has plenty of space to run cables so that you can keep it nice and tidy to allow proper air flow. I would recommend this rack to anyone looking for a rack. March 29, 2013
Lots of features for a great price I honestly wasn't too sure of what to expect when I ordered this. It looked like it had a lot of good ideas, but pictures only told so much. I was pleasantly surprised when we received it. It came fully assembled apart from the doors being packed inside it. When I started using it, I immediately appreciated the extra depth over our old rack, which provided plenty of room for cabling. Each U is marked which has made installing rails a much simpler task. The best part was when I started to install our PDU's, which were made by someone else. They had two standoffs on the rear for rack mounting, but I was very happy to see they worked perfectly with this rack. The price was also very good. It came much cheaper than several others I looked at, as well as some others we have on site. The SR42UB is what I'll be sticking to. October 19, 2012

Depending on the UPS system planning to be housed this unit may work. Do you have the specific make/model of the UPS system(s) being used?

Answer: 
We don't have a cage that will fit in the SR4POST for a tower server but we do have a shelf you can place the server on.

For this check out the SRSHELF4PHD:
http://www.tripplite.com/en/products/model.cfm?txtModelID=4003

This 4 post heavy duty fixed shelf will support up to 250 lbs.

For additional information please reach out to our presales applications team at 773-869-1234 option 1 or presaleshelp@tripplite.com.
