This Middle Atlantic D3 enclosed rack drawer provides a sturdy, safe slide-out metal enclosure that keeps non-rackmountable items safely where you need them — it even features a rear grommet for cable access! The D3 uses three rackspaces and includes spring-loaded latches. Its tough metal construction makes it a perfect complement to your rack. Ball bearing slides ensure smooth, quiet opening and closing, while a fully enclosed top keeps dust and surrounding cables out. You can even remove the bottom of the D3 via quick side releases.
