Middle Atlantic SECL-3 3U Hinged Plexi Security Door

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND SECL-3 is a 3U hinged plexiglass security door designed for use with compatible rackmount enclosures. It provides a transparent barrier that allows visual inspection of rack-mounted equipment while restricting unauthorized physical access. The hinged design enables quick panel opening for routine service without removing fasteners. Installation is handled by systems integrators, AV technicians, or IT infrastructure technicians working on enclosed rack systems.

The SECL-3 is suited for rackmount enclosures in commercial AV, data, security, and control system installations. It occupies 3U of rack space and is used in environments where physical security of rack-mounted gear is required alongside regular visual monitoring of indicator lights or displays. It fits into standard EIA rack configurations as an add-on security accessory.

Installation Notes

Installation is typically performed by a qualified AV technician or systems integrator. Power down all rack-mounted equipment before beginning installation to prevent accidental contact with live components. Follow the enclosure manufacturer's mounting instructions and verify that the door aligns correctly with the rack rails before securing all fasteners. Do not overtighten mounting hardware, as this may crack the plexiglass panel.
