Middle Atlantic Wallmount Shelf - WMS-20

Middle Atlantic WMS-20 Wall Mount Shelf

Overview

The Middle Atlantic WMS-20 is a fixed wall-mount shelf designed for rack-format AV and security equipment that needs a stable surface without a full floor or cabinet enclosure. At 20.63 in. wide and 16.85 in. deep, it handles standard 19-inch rack gear with room to spare for cable dress or a small UPS. The 13.88 in. height accommodates multi-unit stacks or taller chassis — useful when mounting NVRs, patch panels, or small network switches directly to a wall in an IDF closet, back-of-house utility space, or surveillance head-end room. Finish is black. If you're building out a Middle Atlantic rack infrastructure and need a wall-anchored starting point without the footprint of a full enclosure, the WMS-20 is the direct-mount solution.

Compatibility

Sized for standard 19-inch rack equipment across rack mount shelving and accessories. The 20.63 in. interior width accommodates full-width 1U–4U chassis including NVRs, DVRs, network switches, and AV receivers. Pairs naturally with Middle Atlantic's rack panel and blanking plate lines when used as part of a modular wall system. Also compatible with third-party 19-inch rack-format equipment — Hikvision DS-9600/DS-7700 series NVRs, Axis S-series recorders, and similar form-factor units fit within the shelf footprint. Not intended for open-frame or two-post rail mounting — this is a flat surface shelf, not a rail kit. For full network video recorder installations requiring ventilated enclosures or swing-out access, consider a Middle Atlantic rack cabinet instead.

Installation Notes

Shipping weight is 20 lbs (9.1 kg) — account for the shelf's own mass when calculating wall anchor load ratings, particularly on drywall or metal-stud installations where toggle or snap anchors may be inadequate for combined shelf-plus-equipment loads. Wall-anchor selection and torque specs are installer-determined based on wall construction; consult local structural requirements. Black powder-coat finish; no field painting required.
