48U 4-Post SmartRack Premium Open Frame Rack
(no sides, doors or roof)
MODEL NUMBER: SR48UBEXPNDNR3
Description
The SR48UBEXPNDNR3 is an expansion model with no sides, doors or roof. An expansion model is useful
when baying together multiple enclosures. Its integrated baying tabs make it easy to combine multiple
enclosures in rows for data center applications.
The SR48UBEXPNDNR3 houses 3000 lb of standard 19-inch rack equipment in 48U. The 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 and
supports tool-less button-mount 0U installation of up to four compatible PDUs and cable managers.
All components of the SR48UBEXPNDNR3 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 SR48UBEXPNDNR3 comes with heavy duty 3" 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 SR48UBEXPNDNR3 comes with a 5-year product warranty. As part of the SmartRack family, the SR48UBEXPNDNR3 is compatible with Tripp Lite's
extensive range of rackmount accessories, enabling you to customize your solution to meet any requirement.
