RackSolutions 18” Lockable Rackmount Drawers provide a secure enclosure to store equipment that you need on-hand for your server rack, such as USB drives, hardware, cable management supplies, manuals, patch cables, networking tools, and more. Available in sizes from 2U-4U, this drawer features an integrated lock to keep all of your equipment safely stored. The rack-mountable drawer extends up to 20” from the rack on high-quality ball bearing slide rails. With up to 2,000 cubic inches of storage, the 18” drawer is perfect for storing a laptop or full-sized keyboard. The rear access holes allow cables to be routed to any equipment that is stored in the rackmount drawer. An optional bracket is available to fasten the drawer to the rear of the rack to prevent sagging into the rack units below. When rear brackets are used, the mounting depth is between 3”-32” deep.
