Middle Atlantic SSDR-20 Solid Security Door, 20U RMS

Protect critical AV, surveillance and network equipment with the Middle Atlantic by Legrand SSDR-20 solid security door. Built as a 20U RMS, 19" wide door panel, the SSDR-20 gives integrators a simple way to lock down the installer zone while leaving user-accessible devices available in the open portion of the rack. Its keylocked solid design prevents tampering and accidental changes to monitoring and security hardware, improving uptime and reducing service calls. Constructed from heavy-gauge steel with a textured black powder coat finish, the SSDR-20 resists wear in busy racks and fits seamlessly into RK/BRK laminate rack systems. Use it as a partial security panel or as a full door on RK/BRK series racks to standardize installations and cut inventory complexity. Ideal for IT, AV, surveillance and monitoring deployments, this rack accessory streamlines maintenance, enforces access control, and preserves professional aesthetics. Add the SSDR-20 to your next rack build to secure sensitive equipment and simplify site operations.
