Middle Atlantic NM2051H NM Series Horizontal Wall Box Adapter
Overview
The NM2051H is a horizontal wall box adapter designed for Middle Atlantic NM-series rack enclosures, allowing the enclosure to mount flush and securely against a wall surface rather than sitting on a shelf or floor. This adapter solves a common AV and security rack installation scenario where a compact NM enclosure needs to be wall-positioned horizontally — keeping equipment accessible while minimizing floor or furniture footprint. If you are mounting an NM-series enclosure in a closet, equipment room, or wall cavity where vertical orientation is impractical, the NM2051H provides the mechanical interface to do it cleanly.
Compatibility
The NM2051H is designed for use with Middle Atlantic NM-series wall box enclosures. Verify your specific NM enclosure model against Middle Atlantic's NM accessory compatibility matrix before ordering — NM enclosures vary by rack unit height and width, and adapter fitment is model-specific within the series.
Installation Notes
Mount to a solid structural surface capable of supporting the combined weight of the enclosure and installed equipment. Use appropriate fasteners for your wall substrate — the adapter does not supply wall anchors, so select hardware rated for your load on drywall, concrete, or stud mounting as applicable. Confirm the enclosure door swing and ventilation clearances remain unobstructed in the horizontal wall-mounted orientation before finalizing placement.
