The ventilated locking storage cabinet of the Balt FDB AV Cart lets you safely and securely store your AV equipment while allowing heat and sound to escape. The retractable shelf and large height-adjustable top give you plenty of space to hold your presentation materials and equipment. A built-in four-outlet electrical assembly gives you a power supply while the swivel casters let you easily move the unit. Increase your power supply with the optional seven-outlet electrical assembly.
