The RackSolutions Lockable Rackmount Drawers provide a secure enclosure to store any tools and equipment you would need on-hand including USB drives, software, and networking tools. This rack mountable drawer is available in three different sizes ranging from 2U to 4U. The drawers extend on high quality ball bearing slide rails. The 18" version of our server rack drawer is deep enough for a laptop or full-sized keyboard. Rear access holes allow cables to be routed to any equipment that might be stored in these drawers. An optional bracket is available to fasten the drawer to the rear of the rack to prevent sagging into the rack units below. An integrated lock keeps all stored equipment safely stored in your rack.
