Middle Atlantic STL Corner BOX 2 1/2IN D - 5719WH

Middle Atlantic 5719WH Steel Corner Box Fitting

Overview

The Middle Atlantic 5719WH is a 2-1/2-inch-deep steel corner box fitting designed for use with the Middle Atlantic 500 and 700 series raceway and cord cover systems. Corner box fittings solve a specific install problem: where two runs of surface raceway meet at a wall corner, a standard straight section won't make the turn cleanly — the 5719WH provides a finished, code-appropriate transition point that keeps cabling contained through the corner and maintains a consistent white aesthetic across the entire raceway run. If you're deploying cable management in a commercial space where exposed corners need a neat, professional finish, this fitting eliminates the need for field-fabricated workarounds. TAA-compliant, making it suitable for federal, government, and public-sector installations with domestic sourcing requirements. The 5719WH finish is white — specify this part number when your raceway run is white; verify the color of your installed series before ordering.

Compatibility

Designed for the Middle Atlantic 500 series and 700 series steel raceway systems. Confirm your existing raceway series and depth profile before ordering — Middle Atlantic produces multiple raceway depths, and the 2-1/2-inch depth of the 5719WH must match your installed base. This fitting is part of the broader raceway and cord cover fittings family, which includes straight couplers, flat elbows, inside/outside corner pieces, and end caps. For a complete corner transition you may also need inside or outside corner pieces depending on your wall geometry — review the full Middle Atlantic raceway fittings lineup to confirm you have all components required for a finished installation.
