Middle Atlantic MPR RACEWAY56IN. In. - MPR-6A

Middle Atlantic MPR-6A Vertical Power Raceway

The Middle Atlantic MPR-6A is a 56-inch vertical power raceway designed for rack installations where managing power distribution alongside cable routing is a real operational concern. At 3 inches wide and 56 inches tall, it fits alongside standard 19-inch rack frames without consuming valuable equipment rack units, keeping your vertical space organized and your power accessible. The MPR-6A carries ETL recognition, confirming it has been independently tested against applicable safety standards — a requirement on many commercial and enterprise job sites where unrecognized power distribution components will fail inspection.

Key Features

• Configurable Power Architecture: The MPR-6A supports configurable power, meaning outlet count, circuit arrangement, and breaker configuration can be matched to the specific load profile of the rack. That matters in AV and security rack builds where power demand varies significantly between projects — you're not locked into a fixed outlet layout that wastes capacity or leaves circuits short.
• 56-Inch Raceway Length: At 56 inches (142.2 cm), the MPR-6A covers the full usable height of most standard rack enclosures. Cable and power runs stay contained for the entire rack depth rather than spilling at the top or bottom — cleaner installs, faster troubleshooting.
• Slim 3-Inch Profile: The 3-inch (7.6 cm) width is narrow enough to mount vertically alongside the rack rail without interfering with equipment side panels or adjacent cabinet doors. Integrators working in tight multi-bay configurations or wall-mount enclosures will appreciate not having to negotiate clearance.
• ETL Recognized Compliance: ETL recognition (not just self-declaration) means the unit has been third-party evaluated against relevant UL standards. This distinction matters for commercial installations, data closets, and any project subject to authority having jurisdiction (AHJ) review — ETL-recognized components clear permitting faster than uncertified alternatives.
• Manageable Shipping Weight (9.5 lbs): At 9.5 lbs (4.3 kg) unloaded, a single installer can handle positioning and mounting without assistance, which keeps labor costs down on multi-rack deployments.

Integration and Compatibility

The MPR-6A is part of the broader Middle Atlantic power and rack infrastructure line, designed to integrate with Middle Atlantic rack enclosures and open-frame systems. Vertical raceways like this pair naturally with rack accessories including horizontal cable managers and patch panels for a fully organized equipment bay. For projects requiring structured power distribution across multiple racks, confirm outlet configuration and circuit breaker ratings match your aggregate load before specifying. Consult the configurable power options available for this raceway family to select the outlet module appropriate for your installation.

Frequently Asked Questions

Q: What does 'Configurable Power' mean for the MPR-6A?

A: Configurable Power means the outlet layout, circuit count, and breaker configuration of the MPR-6A can be specified to match your rack's load requirements rather than being fixed at manufacture. This allows integrators to tailor the power distribution to the specific equipment being installed.

Q: Is the MPR-6A ETL recognized?

A: Yes. The MPR-6A carries ETL recognition, meaning it has been independently evaluated against applicable safety standards. This is distinct from self-certification and is typically required for commercial installations subject to AHJ review.

Q: What are the physical dimensions of the MPR-6A?

A: The MPR-6A measures 56 inches (142.2 cm) in both height and depth, and 3 inches (7.6 cm) wide. Shipping weight is 9.5 lbs (4.3 kg).

Q: Will the MPR-6A fit alongside a standard 19-inch rack frame?

A: The 3-inch width is designed for vertical side-mount alongside standard rack enclosures without consuming rack unit space or interfering with equipment panels. Verify clearance against your specific enclosure model before ordering.

Q: Does the MPR-6A ship with outlet modules included?

A: Package contents are not confirmed in available evidence. Contact the seller before ordering if outlet modules or specific circuit configurations are required, to confirm what is included with this SKU.

The MPR-6A's 3-inch profile is the spec I'd highlight first for any integrator stacking multiple bays — that slim width is what lets you run vertical power down the side of a rack column without eating into the horizontal equipment space that drives cabinet count and, ultimately, project cost.

Technical Highlights:

• 56-Inch Raceway Height: Covers the full usable height of a standard rack enclosure (142.2 cm), so cable and power management is continuous from top to bottom — no mid-run gaps that create routing problems or code issues on inspected installs.
• Configurable Power: Unlike fixed-outlet PDUs, the configurable power architecture means you spec the outlet and breaker arrangement per job. On a mixed AV/security rack with cameras, NVRs, and PoE switches drawing different loads, that flexibility is practical, not cosmetic.
• ETL Recognition: Third-party safety recognition matters the moment an AHJ inspector walks onto a commercial job site. ETL-recognized components don't generate the same friction as uncertified alternatives — saves time on closeout documentation.

Deployment Considerations:

• At 9.5 lbs unloaded, the MPR-6A is a one-person lift for positioning — but confirm outlet module weight if you're specifying fully loaded units for overhead or side-mount positions in tall enclosures.
• Configurable power is an option, not a guarantee of a specific outlet count or circuit rating — verify exactly what outlet module is included with this SKU before committing to a load plan.

The MPR-6A is the right call for commercial security or AV rack builds where the project spec requires ETL-recognized power distribution and the cabinet layout demands a slim vertical form factor — particularly in multi-bay installations where every inch of horizontal rack space carries a cost.
