Overview

The Middle Atlantic SSDR-21 is a 21-space split security door for Middle Atlantic rack enclosures. Its split-panel design provides selective section access while maintaining a locking security barrier across the full 21-space rack opening, making it well-suited for mid-size AV and IT rack installations with security and operational access requirements.

Description

The SSDR-21 is designed for AV integrators and IT managers who need both physical security and the flexibility to access specific sections of a rack without fully opening the door. The split design divides the 21-space opening into independently operable panels, reducing the disruption of servicing a single unit in a populated rack. The locking mechanism secures both panels when closed, providing consistent access control across the full rack opening. For enclosure compatibility and lock cylinder options, visit .
