Middle Atlantic END Integrated 3 O/l MAG - MDEF3-MG

Middle Atlantic MDEF3-MG Modular Power End Unit, 3-Outlet, Magnesium Finish

Overview

The Middle Atlantic MDEF3-MG is a modular power end unit designed to terminate a ModPower in-surface furniture power assembly with three 5-15R receptacles and a factory-attached 3 ft (0.9 m) cord. If you are building out a collaboration space, conference table, or AV credenza using Middle Atlantic's ModPower system, the MDEF3-MG (often searched as MDEF3 MG) is the end-cap component that closes out the run on the magnesium-finish side — giving you clean, finished aesthetics and accessible power in the same piece. For Middle Atlantic power and furniture solutions, this unit slots directly into the modular architecture without requiring field-wiring of the receptacles themselves.

This unit ships only within the United States and is not available for international orders — a logistics detail worth confirming before specifying it on a project with international delivery requirements.

Key Features

• 3x 5-15R Outlets: Three standard North American 15A/125V receptacles are built into the end unit. For a conference table or credenza power run, that means three independently accessible points for laptops, displays, or AV gear at the terminus of the ModPower strip — no additional outlet modules needed at the end cap.
• 3 ft (0.9 m) Factory Cord: The attached 3 ft cord is intentional for furniture-integrated installations where the power source (floor box, wall outlet, or in-furniture PDU) is close to the furniture run. At 3 ft, the cord is long enough to reach a nearby floor outlet but not so long it creates cable management problems inside a credenza or under-table chase. Verify that your closest power source is within this reach before finalizing the installation layout.
• 5-15R Receptacle Type: The 5-15R designation means these are standard 3-prong grounded outlets — the everyday North American format. Any device with a standard 5-15P plug connects without adapters. This is the right choice for general AV and computing loads; if you need 20A receptacles (5-20R) for higher-draw equipment, that requires a different end unit configuration.
• Magnesium Finish: The magnesium color finish is a specific aesthetic match for Middle Atlantic ModPower components in the same finish family. Color consistency matters in visible furniture installations — a mismatched end cap on a client-facing conference table is the kind of detail that comes back in a punch-list. Confirm all ModPower components on the run are ordered in magnesium if this is your end unit.
• Modular System Integration: The MDEF3-MG is an end unit, not a standalone power strip. It is engineered to terminate a Middle Atlantic ModPower in-surface assembly. This means it connects to the ModPower body modules and provides the finished end with power output — ordering it without the compatible ModPower body units will leave you with an orphaned component. Reference the power distribution category for compatible body modules before purchasing.
• Compact Shipping Profile: Shipping dimensions of 11.1" x 8.1" x 3.2" (282 x 205.8 x 81.3 mm) mean this ships in a small carton. For project deliveries involving multiple table runs, these stack efficiently and are easy to stage on-site without consuming significant storage space.

Integration & Compatibility

The MDEF3-MG integrates exclusively within the Middle Atlantic ModPower in-surface modular power system. It functions as a system end unit — not a universal add-on — so compatibility is determined by the specific ModPower body modules and surface cutout dimensions specified for your furniture build. If you are specifying this unit for a AV furniture power project, confirm the ModPower series and finish (magnesium) match across all components ordered. The 5-15R outlets accept standard North American plugs only; the unit is not rated for international voltages or plug types, consistent with its US-only availability designation.

For integrators sourcing components for a multi-table deployment, consider reviewing the Middle Atlantic product line to match body module outlet counts and configurations to each table run before finalizing the bill of materials. End units like the MDEF3-MG are typically specified one per table run, with body modules filling the center sections.

No IP rating, surge protection rating, or UPS functionality is documented in the available specifications for this unit. If surge suppression or circuit protection is required at the furniture level, specify a ModPower configuration that includes those features rather than relying on this end unit alone.

Frequently Asked Questions

Q: What receptacle type does the MDEF3-MG use?

A: The MDEF3-MG uses 5-15R receptacles — standard North American 3-prong 15A/125V grounded outlets. Any device with a standard 5-15P plug connects directly without adapters.

Q: How long is the power cord on the MDEF3-MG?

A: The MDEF3-MG ships with a factory-attached 3 ft (0.9 m) cord. Plan your installation so the nearest power source — floor box, wall outlet, or PDU — is within this distance.

Q: Is the MDEF3-MG available for international shipment?

A: No. The MDEF3-MG is documented as not available internationally. It is a US-market product with North American 5-15R receptacles and is not rated for international voltages or plug types.

Q: What color finish is the MDEF3-MG?

A: Magnesium. When ordering multiple ModPower components for a single furniture run, confirm all body modules and end units are ordered in the magnesium finish to maintain a consistent appearance.

Q: Can the MDEF3-MG be used as a standalone power strip?

A: No. The MDEF3-MG is a modular end unit designed to terminate a Middle Atlantic ModPower in-surface assembly. It is a system component, not a standalone power strip. Compatible ModPower body modules are required to complete the assembly.

Q: Does the MDEF3-MG include surge protection?

A: Surge protection is not documented in the available specifications for the MDEF3-MG. If surge suppression is required at the furniture level, specify a ModPower configuration that includes a dedicated surge protection module.
