Middle Atlantic Four Gang IN Wall BOX - WSA42-4

Middle Atlantic WSA42-4 Four Gang In-Wall Box

Overview

The Middle Atlantic WSA42-4 is a four-gang in-wall rough-in box designed for structured AV and security cable termination behind finished walls. The WSA42-4 supports wall and rack mounting configurations, making it a practical fit for both new construction and retrofit installations where a clean, recessed termination point is required for low-voltage wiring — keystone panels, cable pass-throughs, and similar structured cabling endpoints in commercial environments. TAA compliance makes it eligible for U.S. federal and government-contract deployments without added sourcing complexity. Shipped dimensions of 11.06" x 9.62" x 7.93" reflect the packaged unit; plan rough-in opening accordingly.

Compatibility

The WSA42-4 is part of Middle Atlantic's Middle Atlantic WallSource series, designed to pair with WallSource four-gang faceplates, dividers, and mounting bracket kits within that same product family. It accommodates standard four-gang low-voltage structured wall plate and bracket accessories. Verify faceplate and divider part numbers against the WallSource series compatibility matrix before ordering — gang count and box depth must align with the specific faceplate and the cable volume expected at the termination point.

Installation Notes

Mount type supports both wall and rack configurations — confirm the target application matches the appropriate mounting orientation before rough-in. As a low-voltage in-wall box, no electrical licensing is typically required for the box itself, but local AHJ requirements for low-voltage rough-in should be verified. The shipped package dimensions (11.06" x 9.62" x 7.93") are packaging dimensions, not the installed box footprint — obtain the WallSource series installation guide for actual rough-in cutout dimensions prior to drywall work. Canadian certification is not listed for this SKU; installations subject to CSA requirements should verify compliance independently.
