Middle Atlantic PTRK-2126MDK 21RU Portable Rolling Rack with Plexi Front Door
Overview
The PTRK-2126MDK is a 21RU portable rolling rack built for deployments where the equipment needs to move — production sets, temporary command posts, mobile security operations centers, and touring AV rigs. At 36.75 in of usable height and 24.5 in of usable depth, it accommodates full-depth 2U and 4U gear including NVRs, network switches, and video management appliances without modification. The plexi front door keeps gear visible and accessible while protecting panels from incidental contact during transit. This rack is part of the broader Middle Atlantic rack and enclosure line, which covers fixed, wall-mount, and portable solutions for security and AV infrastructure.
Compatibility
Fits standard 19-inch rackmount equipment using 10-32 threaded rail hardware — the same thread standard used across virtually all commercial-grade network video recorders, managed PoE switches, patch panels, and UPS units. The 24.5 in usable depth accommodates most 1U–4U appliances; verify chassis depth on deep-server or blade-style gear before ordering. Monitor mounting is supported, making it viable as a self-contained mobile surveillance workstation. Designed to pair with standard rackmount accessories including cable managers, blanking panels, and horizontal power strips available in the rack accessories category. TAA-compliant and manufactured in the USA — meets federal procurement requirements for government and defense deployments. Consult a rack cooling and airflow guide before loading high-density equipment, as mobile enclosures have limited passive airflow compared to open-frame alternatives.
Installation Notes
External dimensions are 27.91 in W × 46.95 in H × 26.93 in D — confirm doorway and elevator clearances before deploying on-site. Weight capacity is 500 lbs; factor in the rack's own weight when estimating floor load and lift requirements. The wood laminate top provides a working surface for monitors or peripherals. Casters are included for mobility; verify floor surface compatibility (hard floor vs. carpet) for smooth transit with loaded weight.
