Middle Atlantic STL Ext. BOX Adapter Ivor - V5751A

Middle Atlantic V5751A Steel Raceway Extension Box Adapter, Ivory

Overview

The Middle Atlantic V5751A is a steel extension box adapter fitting designed for the Middle Atlantic 500 and 700 series deep flush-type raceway systems. At 4.75 in wide, 3 in tall, and 1.88 in deep, this adapter provides the transition depth needed when a standard raceway outlet or device box falls short of the wall surface — a common issue in retrofit installations where wall material thickness varies or when adding devices to an existing cable management raceway run. The V5751A ships in ivory to match ivory-finish raceway sections; using a mismatched color in a finished commercial interior is the kind of detail that draws facility manager complaints. TAA compliant, making it eligible for government and federal procurement projects where Trade Agreements Act conformance is a contract requirement.

Compatibility

Designed specifically for the Middle Atlantic 500 series and 700 series deep flush-type steel raceway systems. Confirm your existing raceway series before ordering — Middle Atlantic produces multiple raceway families (surface, flush, deep flush) and extension fittings are not cross-compatible between them. This fitting is for the deep flush type variant of the 500/700 series only. Match the ivory color code to your installed raceway finish; Middle Atlantic offers the same adapter in alternative finishes for white or brown raceway runs.

Installation Notes

Verify wall-surface offset before ordering — the 1.88 in extension depth is fixed, so measure the gap between the raceway body and the finished wall plane to confirm this adapter closes it correctly. Standard steel raceway installation tools apply; no specialized hardware is documented for this fitting beyond what the base 500/700 series raceway requires.
