Middle Atlantic Nonmetallic Rectangular F - 880MP

Middle Atlantic 880MP Nonmetallic Rectangular Floor Box

Overview

The Middle Atlantic 880MP is a nonmetallic rectangular floor box designed for structured wiring and modular connectivity installations in commercial environments. Part of the Modulink 880MP series from Legrand AV, this unit provides a compact, durable housing for floor-level cable management and outlet distribution — a practical choice for conference rooms, open office plans, classrooms, and AV-integrated spaces where surface-mount conduit isn't an option and clean underfloor access is required.

At 4.13 in wide × 6.25 in tall × 7.13 in deep (10.5 × 15.9 × 18.1 cm), the 880MP fits standard concrete floor cutouts while providing enough interior depth to accommodate standard gang inserts, outlet modules, and low-voltage media plates without crowding. The nonmetallic (plastic) construction keeps the box electrically non-conductive and corrosion-resistant — relevant in environments where moisture intrusion or grounding complications are a concern.

Key Features

• TAA Compliant: The 880MP meets Trade Agreements Act requirements, making it eligible for federal government procurement, GSA schedule projects, and public-sector installations where TAA compliance is a contractual requirement. If your project has a Buy American or TAA clause, this box qualifies.
• Compact Rectangular Footprint (4.13 × 6.25 in): The narrow profile fits tighter floor cutout constraints compared to larger square boxes, giving installers more flexibility in finished concrete or raised-floor tile grids where real estate is limited.
• 7.13 in Interior Depth: Provides adequate clearance for standard duplex outlet modules, low-voltage inserts, and cable slack loops — reducing the chance of a too-shallow box forcing a rework mid-install.
• Nonmetallic (Plastic) Construction: Eliminates the need for bonding or grounding the box itself, simplifies rough-in in environments with moisture exposure, and won't corrode in below-slab or damp concrete applications.

Integration & Compatibility

The 880MP is engineered as part of Middle Atlantic's Modulink series, designed to accept compatible gang inserts and low-voltage media plates. Verify insert compatibility with the specific Modulink 880MP series accessories before ordering — not all standard floor box inserts are dimensionally interchangeable across brands. Confirm your finished floor depth and cutout template match the 7.13 in depth and the 4.13 × 6.25 in opening before rough-in, particularly in poured concrete applications where rework is costly.

Frequently Asked Questions

Q: Is the Middle Atlantic 880MP TAA compliant?

A: Yes. The 880MP carries TAA (Trade Agreements Act) compliance, making it eligible for federal, state, and public-sector projects with TAA or Buy American procurement requirements.

Q: What are the dimensions of the 880MP floor box?

A: The 880MP measures 4.13 in wide × 6.25 in tall × 7.13 in deep (10.5 × 15.9 × 18.1 cm).

Q: Is the 880MP a metallic or nonmetallic box?

A: It is nonmetallic (plastic construction), which means no bonding or grounding of the box itself is required and it is corrosion-resistant for damp or below-slab installations.

Q: What series does the 880MP belong to?

A: The 880MP is part of Middle Atlantic's Modulink 880MP series of rectangular plastic floor boxes, designed for modular insert compatibility in commercial flooring applications.

Karl Wilson

The 880MP is a compact nonmetallic floor box that checks the TAA box for government and public-sector AV/structured-wiring projects — a spec that eliminates it from the bidding process if you miss it at the takeoff stage. At 7.13 in deep and 4.13 × 6.25 in in plan, it fits where larger square boxes don't, and the plastic shell sidesteps grounding complications that come with metallic boxes in wet or below-grade pours.

Technical Highlights:

• TAA Compliance: Qualifies for GSA schedule and federally-funded projects with Buy American or TAA clauses — confirm at bid time, not after award.
• 7.13 in Depth: Enough clearance for duplex outlet modules and low-voltage inserts with cable slack — shallower boxes in this footprint class frequently force rework.
• Nonmetallic Construction: No bonding jumper required; corrosion-resistant in damp concrete applications where steel boxes oxidize and complicate inspections.

Deployment Considerations:

• Confirm the 4.13 × 6.25 in cutout template against your finished floor tile grid before concrete pour — dimensional mismatches in poured slabs are expensive to correct.
• Verify Modulink series insert compatibility before procurement; not all standard gang inserts fit across floor box brands, and the 880MP is designed for its own series accessories.

Best fit for TAA-required commercial AV rough-ins — conference rooms, classrooms, and open-plan offices where clean floor-level connectivity is specified and a metallic box would complicate the grounding plan.
