Aluminum Rack Mount Chassis. 4U (7") height, ~22" deep. Removed from decommissioned Agilent equipment. There is an aluminum shelf (with holes cut from previous use). Please see my other listing for the front panel with many RF passthrough connectors. This is a great platform for a rack mount project, with good venting and nice quality. 

Chassis weight is 12.2 lbs. 

Note: Rack ears will likely be removed and packed separately so they aren't damaged in shipping.
