The 30-Capacity Charging Cart with Keypad Lock combines convenience and security in a mobile charging solution. Solid steel construction keeps devices safe, and no more worrying about misplacing a key thanks to a programmable keypad lock. Rubber-coated dividers won't scratch devices and also help provide impact protection during transit. Non-skid casters let you smoothly move the cart down hallways and across carpet or hard surfaces. It's an incredibly useful tool for schools, libraries or any IT environment.
