Middle Atlantic Double Blanking Plate-bra - 431BR

Middle Atlantic 431BR Double Blanking Plate — Brass

Overview

The Middle Atlantic 431BR is a double blanking plate finished in brass, designed to cover unused openings in Middle Atlantic in-floor service fitting assemblies. When a floor box or service fitting is partially populated — leaving one or more ports unoccupied — an exposed opening is both a trip hazard and a point of ingress for debris and liquids. The 431BR closes off a double-width slot with a finish-matched brass cover, keeping the assembly flush and protected. TAA-compliant, making it appropriate for government, federal, and public-sector installations where Trade Agreements Act sourcing is required.

Compatibility

The 431BR is designed for Middle Atlantic in-floor service fitting systems. It covers a double-width opening within those assemblies. Verify the specific series and opening count against your installed floor box configuration before ordering — Middle Atlantic offers single and double blanking plate variants to match different slot widths. The brass finish is intended for installations where the floor box hardware is also brass-finished; mismatched finishes in high-visibility environments (boardrooms, lobbies, executive spaces) are a common field mistake.

Installation Notes

Drop-in installation — no tools or hardware noted in evidence. Confirm the opening count and plate width match your floor box configuration before installation. The brass finish is a fixed attribute of the 431BR; if your service fitting uses a different finish, select the appropriate finish variant from the Middle Atlantic blanking plate line.
