Middle Atlantic Floor BOX W/895T Brass CO - 862DB

Middle Atlantic 862DB Floor Box Assembly for Wood or Concrete Floors

Overview

The Middle Atlantic 862DB is a compact PVC floor box assembly designed for structured cabling and power distribution in commercial flooring environments — wood subfloor or poured concrete. At 4.25 in x 4.25 in x 4 in, it fits a standard poke-through footprint without requiring oversized core drilling or custom cutouts, keeping installation time predictable on both new construction and retrofit jobs. The 862DB ships as an assembly with a 895T brass cover, giving you a finished, professional-grade floor termination point without sourcing hardware separately. TAA compliance makes it a clean procurement choice for federal facilities, government contractors, and institutional buyers subject to trade agreement requirements.

Key Features

• 4.25 in x 4.25 in x 4 in PVC Body: The compact square footprint fits standard floor box rough-in cuts — no oversized core drilling needed. PVC construction resists moisture wicking in concrete slabs, a common failure point for metal boxes in below-grade or slab-on-grade installations.
• 4 in Depth: Provides sufficient interior clearance for low-voltage connectors, keystone jacks, or power modules without bottoming out on cable bend radius — critical when you're terminating Category cable or coax at the floor level.
• 895T Brass Cover Included: The brass cover is included in the assembly, so you're not hunting down a separate cover SKU. Brass handles foot traffic and rolling loads better than plastic lids, and the finished appearance suits open office, conference room, and lobby installations where aesthetics matter.
• Compatible with Wood and Concrete Floors: Dual-substrate compatibility means one SKU covers both new poured-slab construction and wood subfloor retrofits — reduces SKU proliferation on multi-floor projects with mixed construction.
• TAA Compliant: Verified TAA compliance means the 862DB qualifies for GSA schedule purchases, federal agency projects, and any contract requiring products manufactured or substantially transformed in TAA-designated countries. No compliance workarounds needed at bid time.
• PVC Floor Box Series: Part of Middle Atlantic's established floor box line, the 862DB integrates with the broader Middle Atlantic infrastructure ecosystem — relevant when specifying alongside rack units, panels, and structured cabling in the same facility.

Integration and Compatibility

The 862DB is a passive enclosure — it accepts standard keystone inserts, modular power modules, and low-voltage connectors sized for a standard floor box opening. Confirm insert dimensions against the 4.25 in x 4.25 in interior footprint before specifying non-standard modules. For AV and security integrators running structured network cabling to floor-level connection points in conference rooms or security operation centers, this box provides a clean, code-compliant termination without exposed cable runs. Pair with appropriate conduit fittings for below-slab conduit entries per local electrical code. TAA-compliant sourcing supports federal and access control infrastructure projects where supply chain documentation is required at contract close.

Frequently Asked Questions

Q: Is the Middle Atlantic 862DB TAA compliant?

A: Yes. The 862DB is verified TAA compliant, making it eligible for GSA schedule purchases and federal procurement contracts requiring Trade Agreements Act compliance.

Q: Does the 862DB work in both wood and concrete floors?

A: Yes. The 862DB is designed for installation in either wood subfloor or poured concrete applications, covering both new construction and retrofit scenarios with a single SKU.

Q: What are the dimensions of the 862DB?

A: The 862DB measures 4.25 in wide x 4.25 in deep x 4 in tall (10.8 cm x 10.8 cm x 10.2 cm).

Q: Is a cover included with the 862DB?

A: Yes. The 862DB ships as a complete assembly including the 895T brass cover — no separate cover purchase required.

Q: What material is the 862DB floor box made from?

A: The floor box body is PVC, which resists moisture absorption in concrete slab installations where metal boxes can corrode or wick ground moisture over time.

James Everett

The 862DB is one of those components that looks trivial on a bill of materials but causes real problems when you spec the wrong one. The 4 in depth is the spec I check first — it is tight enough that you need to think about connector profiles before you commit. On a conference room floor box running Cat6A with a 90-degree keystone, you are at the limit. The 862DB works, but plan your termination layout before pulling cable.

Technical Highlights:

• 4.25 in Square Footprint: Matches standard floor box rough-in dimensions — no custom cutting on concrete or subfloor, which keeps the flooring contractor and the low-voltage crew from fighting over the schedule.
• PVC Construction: In slab-on-grade or below-grade environments, PVC outlasts steel in the presence of ground moisture — a practical advantage on first-floor commercial installs where the slab sees seasonal humidity variation.
• TAA Compliance: Verified at the SKU level, not just a brand-level claim. On federal facility projects or GSA-schedule jobs, that distinction matters at contract close when procurement asks for documentation.

Deployment Considerations:

• The 895T brass cover is included in the assembly — confirm this before adding a separate cover line item to the quote or you will order a duplicate and create a return.
• At 4 in interior depth, verify the combined stack height of your inserts and cable connectors before finalizing the module selection. Low-profile keystone jacks are the safer call in this box.

The 862DB is the right call for open-plan office, conference room, and lobby floor termination points on TAA-restricted projects where you need a finished brass cover appearance and a PVC body that holds up in mixed concrete and wood subfloor construction environments.
