The Middle Atlantic Vented Security Door VSDR-20 is a unique solution that allows you to secure a select portion of rack-mount equipment by covering only a limited area of the front rack with a security door. Mount equipment behind the vented door to prevent unauthorized users from accessing and tampering with equipment. Security-sensitive equipment sits safely behind this door while other equipment remains completely accessible in the same rack. This unit can also act as a full door on RK and BRK series racks.
