Middle Atlantic DOOR-S – Essex Solid Door for MMR and QAR Racks

Product Overview

The Middle Atlantic DOOR-S is a solid door designed for Essex MMR Series and QAR Series racks, giving integrators a clean way to enclose equipment from either side of the frame. Because the same door fits both the front and rear of the rack, one part number covers multiple positions in a deployment. The series is offered in 10, 12, 16, 18, 27, and 42 rack unit heights to match the full range of Essex enclosures. A solid panel conceals cabling and gear for a finished appearance in client-facing and back-of-house spaces alike.

Product Description

Enclosing a rack is the last step that separates a tidy commercial AV installation from an unfinished one. The DOOR-S solid door closes off Essex MMR Series and QAR Series racks, hiding patch fields, power distribution, and source equipment behind a uniform panel. For procurement teams, the front-and-rear compatibility simplifies ordering: the same SKU can be specified for either face of the rack, or both, without tracking separate front and rear part numbers.

Size selection follows the rack height. The DOOR-S10 covers 10 RU enclosures, with DOOR-S12, DOOR-S16, DOOR-S18, and DOOR-S27 stepping through mid-size configurations, and the DOOR-S42 enclosing full-height 42 RU racks. That range makes the series practical across an entire project, from compact equipment closets serving a single conference room to head-end racks supporting a whole building. Specifying the matching Essex series door also preserves the rack manufacturer's fit and finish, which matters when systems are inspected at commissioning or handed off to facilities staff. As a factory-matched accessory, it integrates with the Essex rack frame as designed rather than relying on aftermarket adaptation.

Frequently Asked Questions

Which racks does the DOOR-S fit?
The DOOR-S is designed for Middle Atlantic Essex MMR Series and QAR Series racks. Match the door's RU size to the height of your rack.

Can I use the same door on the front and rear of the rack?
Yes. The DOOR-S fits both the front and rear of compatible Essex racks, so one part number covers either position.

How do I choose the right size?
Order the door that matches your rack's height in rack units: 10, 12, 16, 18, 27, or 42 RU. The SKU suffix indicates the size, for example DOOR-S18 for an 18 RU rack.

Should I choose a solid or vented door for my AV installation?
A solid door provides a clean, concealed appearance. If your equipment depends on front-to-back airflow through the door panel, review your thermal plan; Middle Atlantic also offers vented and plexi door options for the Essex line.

Does an enclosed door help with system handoff?
Yes. Closing off the rack protects connections from casual contact and gives facilities and IT staff a finished, serviceable enclosure at commissioning.

What warranty and support apply?
The DOOR-S is covered by Middle Atlantic's manufacturer warranty, and Creation Networks provides specification assistance and post-sale support for commercial projects.
