The 33X Series Cabinets are built to conform to the widely-used Caltrans TEES standards. This cabinet style features a 19″ rack for mounting the equipment in the cabinet. The 33X Cabinets utilize rack-mount equipment for the output file, input files, PDA, and other components that are mounted in the cabinet. This makes it simple to install rack mount equipment like Ethernet switches, fiber panels, shelves, and more. The cabinets all feature both front and rear doors to access both sides of the racks.
