Middle Atlantic Desktop Rail Rack DR Series DR-12 Steel Black Powder Coat finish

Middle Atlantic DR-12 12RU Desktop 2-Post Rack

The Middle Atlantic DR-12 is a 12-rack-unit desktop 2-post rail rack built for integrators who need a compact, structured equipment bay without committing to a full floor-standing enclosure. At 22.95 inches tall and 19.27 inches wide, the DR-12 fits cleanly on a workbench, equipment shelf, or operations counter — the right form factor when you need organized rack space but not a full cabinet footprint. Whether you're deploying a small NVR, a patch panel stack, or a focused access control head-end, the DR-12 provides a professional mounting solution without the bulk.

Overview

Part of Middle Atlantic's DR Series desktop rack line, the DR-12 (often searched as DR 12) ships as a knockdown unit — meaning it arrives flat-packed and assembles in the field, reducing shipping cost and making it easier to move into tight equipment rooms. The steel construction with black powder coat finish gives it the durability expected in commercial security and AV deployments. TAA compliance makes it eligible for government and institutional procurement that requires US trade agreement sourcing. The 10-32 threaded rail type is the standard for rack-mount security and AV equipment, so virtually every NVR, managed switch, or UPS in a typical security integrator's kit will drop straight in.

For a broader look at the Middle Atlantic rack and enclosure catalog, the DR Series sits alongside wall-mount, swing-out, and full-enclosure options for different deployment footprints. If you're selecting rack infrastructure for a security or AV deployment, the racks and enclosures category covers the full range of form factors.

Key Features

• 12 Rack Units / 21 in Usable Height: 12RU gives you enough room to house a mid-range NVR, a PoE switch, a patch panel, and a UPS simultaneously — without the wasted vertical space of an oversized rack that's half-empty. The 21 inches of usable internal height is the number that matters for actual equipment fit.
• 75 lb Weight Capacity: A 75-pound load rating handles the realistic weight of a dense 12U deployment — a heavy NVR with drives, a managed switch, and a small UPS will typically come in under 60 lbs. You're not going to strain this rack with standard security head-end gear.
• 10-32 Rail Type: The 10-32 threaded hole pattern is universal for rack-mount security, networking, and AV gear. No cage nuts needed — equipment with standard rack screws installs directly, saving time during commissioning and avoiding the frustration of loose cage-nut panels on a small open rack.
• Steel Construction with Black Powder Coat Finish: Steel gives this rack meaningful rigidity compared to aluminum-frame alternatives at this price point. The powder coat finish resists scratching during installation and in environments where the rack is exposed and visible — front-of-house operations rooms, retail back-office, or command centers where appearance matters.
• Desktop / 2-Post Open Form Factor: Open 2-post construction means unrestricted cable access from any direction — front, rear, or sides — which cuts installation time significantly versus a closed enclosure. Cable management is the integrator's call, not forced by the rack geometry.
• Compact Footprint — 11.55 in Depth: At under 12 inches deep, the DR-12 fits on a standard equipment shelf or desk surface without overhanging. This is the spec that differentiates it from 4-post racks that require 24–36 inches of depth clearance. If your equipment room is tight or your client's counter space is limited, depth matters.
• TAA Compliant (Knockdown): TAA compliance means this rack is eligible for federal, state, and institutional contracts that specify Trade Agreements Act sourcing. The knockdown construction (country of origin: Mexico) satisfies the TAA standard. If your project has Buy American or TAA requirements, the DR-12 checks that box without a special procurement path.

Integration & Compatibility

The DR-12's 10-32 threaded rails accept standard rack-mount equipment from virtually every security and networking manufacturer — NVRs, PoE switches, patch panels, KVM units, and UPS systems all mount without adapter hardware. The 19.27-inch width conforms to the EIA-310 19-inch rack standard, so any equipment spec'd for a standard rack will fit. For deployments pairing this rack with network video recorders or managed PoE switches, no rail adapters or specialty hardware are required.

The open 2-post design does not provide the physical security or dust protection of a closed enclosure — if the deployment environment requires locking or environmental protection, consider a Middle Atlantic rack enclosure with doors and side panels instead. For deployments where the rack will be visible and unsecured, plan cable management accessories separately, as the DR-12 does not include integral cable management arms or rings.

Frequently Asked Questions

Q: Is the Middle Atlantic DR-12 TAA compliant?

A: Yes. The DR-12 is TAA compliant, with a federal ops country of origin of Mexico. It is eligible for government and institutional procurements requiring Trade Agreements Act sourcing.

Q: What rail thread type does the DR-12 use?

A: The DR-12 uses 10-32 threaded rails — the standard rack rail type for security, networking, and AV equipment. No cage nuts are required; equipment with standard 10-32 rack screws installs directly.

Q: How much weight can the DR-12 hold?

A: The DR-12 is rated for a 75 lb (34 kg) weight capacity. This is sufficient for a dense 12U security head-end deployment including an NVR with drives, a managed switch, and a small UPS.

Q: What is the actual usable rack space in the DR-12?

A: The DR-12 provides 12 rack units of mounting space with 21 inches (53.3 cm) of usable internal height. The overall unit height is 22.95 inches.

Q: Can the DR-12 be used as a wall-mount rack?

A: The DR-12 is specified as a desktop rack. It is not rated or designed for wall mounting. For wall-mount applications, a dedicated wall-mount rack enclosure from the Middle Atlantic line would be the appropriate choice.

Q: Does the DR-12 ship assembled or as a kit?

A: The DR-12 ships as a knockdown (flat-pack) unit and is assembled on-site. This reduces shipping cost and makes it easier to transport into equipment rooms with restricted access.

I spec the DR-12 regularly for compact security head-ends where the integrator needs a structured rack solution but the site doesn't justify a full floor-standing enclosure. The 75 lb weight capacity and 12RU of 10-32 threaded space covers most single-location deployments — an NVR, a PoE switch, a patch panel, and a small UPS fit comfortably without approaching the load limit.

Technical Highlights:

• 12RU / 21 in Usable Height: Enough vertical space to organize a complete small-site head-end — NVR, switch, panel, and power — without the wasted rack space of an oversized unit that's only half-populated.
• 11.55 in Depth: Under 12 inches of depth means this fits on a standard equipment shelf or desk without clearance problems. That's the spec that saves you on tight installs where a 4-post rack simply won't fit.
• TAA Compliance: The DR-12 satisfies TAA sourcing requirements (Mexico origin), which matters on government, education, and institutional projects where procurement specs the standard. No special procurement path needed.

Deployment Considerations:

• The open 2-post design gives you full cable access from all sides — plan your cable routing before you populate the rack, since there are no integrated cable management arms. Add a dedicated cable management panel if the deployment needs a clean appearance.
• At 75 lbs max, the DR-12 will handle most 12U security deployments, but verify the combined weight of your NVR (with drives loaded), switch, and UPS before spec'ing. Heavy UPS units alone can run 20–30 lbs, which leaves meaningful headroom but not unlimited.

The DR-12 is the right call for a retail back-office or small commercial site where you want a professional rack-mount deployment without the footprint or cost of a full enclosure — and where TAA compliance is a procurement checkbox rather than an afterthought.
