Middle Atlantic Smoked Tempered Glass Front Door Fits 12 Space BRK Obrk and Mbrk Series - RK-GD12

Middle Atlantic RK-GD12 Smoked Tempered Glass Front Door for 12U Racks

Overview

The Middle Atlantic RK-GD12 is a smoked tempered glass front door designed as a direct replacement or add-on for 12-rack-unit open-frame and enclosed rack enclosures. At 20.93 in tall and 18.69 in wide, the RK-GD12 provides front-panel visibility into rack contents without requiring the door to be removed — useful in AV equipment rooms, server closets, and security head-end installations where status lights and display readouts need to be visible during normal operation. Smoked tempered glass keeps the interior view accessible while reducing visual clutter in client-facing spaces. Depth of 2.3 in keeps front clearance impact minimal on shallow rack footprints.

Compatibility

The RK-GD12 is engineered specifically for Middle Atlantic rack enclosures in the following series:

• BRK Series — the base open-frame rack enclosures this door was designed around
• OBRK Series — open-bay rack variant
• MBRK Series — Middle Atlantic's monitored rack enclosure variant

Compatible with 12 RU configurations only — do not attempt to fit this door on 8U, 16U, or 20U BRK/OBRK/MBRK units; each rack unit count has its own matched door SKU. Verify your rack's base series and rack unit count before ordering. Review Middle Atlantic's rack accessories catalog to confirm the correct door variant for your enclosure.

Installation Notes

Shipping weight is 8 lbs (3.6 kg) — account for this when planning overhead or wall-mount rack deployments where total enclosure weight is a factor. The 2.3 in depth addition to the front of the rack must be factored into room clearance calculations, particularly in tight equipment closets or against knee walls. For AV and security integrators managing cable entry and airflow planning, consult the rack mounting guide for BRK series enclosure configurations before finalizing front-door selection.
