Middle Atlantic SSDR-20 - 20SP Split Security Door

Product Overview

The Middle Atlantic SSDR-20 is a 20-space split security door designed for rack enclosures where independent upper and lower access is required. The split design allows technicians to access the upper or lower portion of the rack without exposing the entire front panel, improving operational security in shared or semi-public equipment spaces. It is engineered for permanent AV and IT installations requiring both physical access control and operational flexibility.

Product Description

The SSDR-20 split security door retrofit provides dual-zone front access control for 20-space rack enclosures, dividing the rack front into independently lockable upper and lower sections. This configuration is particularly valuable in environments where multiple personnel require access to different rack zones — for example, a facility where AV operators access lower-zone media equipment while IT staff manage upper-zone network hardware — without granting unrestricted access to the full rack front. Each door half operates on independent hinges and lock cylinders, allowing separate keying for different access zones if required. The heavy-gauge steel construction resists forced entry attempts consistent with commercial security requirements. Ventilation slots or perforations in the door panel maintain airflow continuity across the rack front without compromising physical security. The door integrates with standard Middle Atlantic rack uprights using the existing attachment hardware, minimizing retrofit complexity. The powder-coat finish matches Middle Atlantic's rack enclosure finishes for a cohesive, professional installation appearance. Integrators and facilities managers specify the SSDR-20 when client security requirements exceed what a single-panel door can provide in multi-user rack environments.
