Middle Atlantic PTRK-21MDK 21RU Portable Rolling Rack with Plexi Front Door

Overview

The PTRK-21MDK is a 21RU mobile rolling rack built for deployments where equipment needs to move — staging environments, touring AV rigs, temporary command posts, and security integration jobs where the rack travels before it parks permanently. At 27.91 in wide × 46.95 in tall × 23.93 in deep, it fits standard rack-mount gear while remaining passable through most commercial doorways without disassembly. The plexi front door keeps dust and fingers off installed gear while preserving visibility into indicator lights and front-panel status — useful on a live rack in a crowded equipment room or mobile command unit. TAA-compliant and manufactured in the USA, making it a viable option for government and federally funded projects with domestic sourcing requirements.

Compatibility

Accepts any standard 19-inch rack-mount equipment on 10-32 threaded rails — the industry-standard threading used by virtually all commercial network switches, NVRs, video management servers, patch panels, and UPS units. The 21.5 in usable depth accommodates most 1U–4U appliances including deep network video recorders and dense PoE switches. Monitor mounting is supported, which makes this practical as a self-contained mobile surveillance system or field-deployable AV station. The wood laminate top provides a stable work surface above the rack column. Not designed for permanent wall or floor anchoring — this is a roll-in, roll-out chassis; for fixed installations consider a static Middle Atlantic rack enclosure from the same product line.

Installation Notes

500 lb weight capacity — distribute load evenly across the rack column; concentrate heavy equipment (UPS, dense NVRs) toward the bottom to lower the center of gravity and reduce tip risk when rolling. Usable interior height is 36.75 in (93.3 cm), which is less than the external 46.95 in due to caster height and frame structure — verify your tallest chassis fits within 21 RU before ordering. 10-32 rail threading is standard, but confirm your specific gear uses 10-32 cage nuts or screws; some server equipment ships with M6 hardware requiring an adapter. For security integrations pairing this with NVRs or recording appliances, plan cable management before populating — the mobile form factor limits rear-panel access once fully loaded.
