Model Number: SR42UBEXPND


  • 42U SmartRack Premium open frame rack
  • 4 interior vertical posts with unthreaded square hole openings
  • Standard 24" (600mm )width and 42" (1050mm) depth for optimizing floor space
  • Ships fully assembled
  • 3000 lb stationary / 2250 lb rolling load capacity

  • Rolls through standard 7 foot doorway
  • Includes 50 pieces of M6 cage nuts and 50 pieces of M6 screws (equipment mounting hardware)

The SR42UBEXPND is 42U SmartRack enclosure with NO doors and NO side panels. The 'EXP' version is an expansion model used when several cabinets are bayed together. Its integrated baying tabs make it easy to combine multiple enclosures in rows for data center applications. This enclosure is also compatible with hot-aisle/cold-aisle configurations.

The SR42UBEXPND houses 3000 lb of standard 19-inch rack equipment in 42U. Its front and rear pairs of vertical rails have square mounting holes that are adjustable in quarter-inch increments from 4 to 37 inches. Adjustment is quick and an easy-view depth index ensures consistent rail placement without requiring time-consuming measurements. Each rack space within the enclosure is numbered for ready reference.

Two of the adjustable vertical mounting rails support toolless button-mount 0U installation of up to four compatible PDUs and cable managers. This feature makes it easier to route cabling to rack equipment and reduces cord clutter.

All components of the SR42UBEXPND are grounded to the enclosure frame. Front and rear threaded grounding points are provided for connection to the facility earth ground.

To simplify deployment, the SR42UBEXPND comes with preinstalled casters that enable it to be easily maneuvered into the desired location, where it can be secured by adjusting the preinstalled levelers. Note: the casters are intended for minor position adjustments and are not designed for moving the enclosure over long distances.

The SR42UBEXPND comes with a 5-year product warranty. As part of the SmartRack family, the SR42UBEXPND is compatible with Tripp Lite’s extensive range of rackmount accessories, enabling you to customize your solution to meet any requirement.

Purchased one of these to clean up the server room when I started a new job. Was delivered in tact and ready to go. The removable side panels make it easy to add and remove equipment and manage cables. March 4, 2014
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
I ordered two of these racks for our office move. They were delivered in tact and with casters so very easy to move to the server room. Easy to attach to each other. I like that they have a roof to hold cable. I also like the option to order panels for the sides and locking doors if I want to enclose at some point down the road. Also note that they come with a bag of hardware that definitely comes in handy. March 19, 2013

I'm looking at the SR42UBEXPND rack and want to know if it uses all of the shelf and other accessories that the SR4POST rack uses.
