Middle Atlantic CM2-BL-GY 2A Blank Module

The Middle Atlantic CM2-BL-GY is a 2A blank module in light gray, built to fill unused bays in Middle Atlantic's CM2 rack and enclosure systems. When you're populating a rack with switches, patch panels, and PDUs, gaps between components look unfinished and leave openings for dust intrusion and stray airflow. The CM2-BL-GY closes those gaps with a matched-finish panel instead of leaving raw cutouts exposed.

Overview

CM2-BL-GY is sized for a single 2A opening within the CM2 modular series, which uses standardized bay widths so blanks, vented panels, and active modules can be mixed within the same frame without custom fabrication. The gray finish is intended to match Middle Atlantic's light gray (LT GY) enclosure line, so a rack built out with CM2 components keeps a consistent look front-to-back rather than mixing colors panel to panel.

Key Features

• 2A module sizing: Matches the CM2 platform's standard bay dimension, so it drops into an open 2A slot without trimming or adapter hardware — useful when a rack layout changes and a bay that once held active gear needs to be closed off cleanly.
• Light gray (LT GY) finish: Matches Middle Atlantic's light gray enclosure and module line, which matters in visible equipment rooms, AV closets, or any install where a mismatched black blank against a gray rack face reads as an afterthought.
• TAA compliance: Meets Trade Agreements Act sourcing requirements, which is a hard gate for federal, state, and many prime-contractor procurements — if you're quoting a government or GSA-adjacent job, a non-TAA blank panel can stall the whole PO regardless of price.
• Dedicated blank (non-vented): A solid blank, not a passthrough or vented panel, so it seals the bay rather than passing cable or airflow — pick this specifically when you want the opening fully closed rather than ventilated.

Integration & Compatibility

CM2-BL-GY is built for the CM2 module family, so it's intended to sit alongside other CM2-series blanks, vented panels, and equipment modules in the same frame rather than as a universal rack-blank substitute. If you're speccing a full rack, pair it with the broader Middle Atlantic catalog for matching CM2 modules, and check rack mount accessories for the vented or active panel options that share the same 2A footprint. For teams planning out a full enclosure buildout, a network video recorder or switch deployment sharing the same rack is a good prompt to review overall PoE switch and patch panel layout before finalizing which bays get blanked versus populated.

Frequently Asked Questions

Q: Is the CM2-BL-GY TAA compliant?

A: Yes, the CM2-BL-GY (Middle Atlantic 2A Blank Module LT GY) is TAA compliant, which supports federal and GSA-adjacent procurement requirements.

Q: What color is the CM2-BL-GY?

A: It ships in light gray (LT GY), matched to Middle Atlantic's light gray enclosure and CM2 module finish.

Q: What size bay does the CM2-BL-GY fit?

A: It's a 2A module, sized to fill a single 2A opening in Middle Atlantic's CM2 modular rack system.

Q: Is the CM2-BL-GY vented or solid?

A: It's a solid blank module, intended to close off an unused bay rather than pass airflow or cable.

James Everett

The CM2-BL-GY is a small part that solves a real problem: an open 2A bay in an otherwise finished CM2 rack. I spec these whenever a customer's equipment list doesn't fill every module slot and they care about how the rack looks in a server room or AV closet that gets client walkthroughs.

Technical Highlights:

• 2A sizing: Fits the standard CM2 bay dimension directly, so it installs without cutting or adapting the frame.
• LT GY finish: Matches Middle Atlantic's light gray module line, avoiding the mismatched black-blank-in-a-gray-rack look.
• TAA compliance: Clears sourcing review on federal and prime-contractor jobs where non-compliant components get a BOM line rejected outright.

Deployment Considerations:

• Order CM2-BL-GY specifically for the light gray CM2 line — confirm your enclosure color before ordering, since Middle Atlantic runs both black and gray variants across its module families.
• This is a solid blank, not a vented panel — if the bay needs airflow, look at a vented CM2 module instead of this part.

Right fit for finishing out a light-gray CM2 rack build where every bay needs to be either populated or blanked before a client or auditor walkthrough.
