Middle Atlantic PTRK-2126 with Locking Front & Rear Door ***Drop Ship Only***

Middle Atlantic PTRK-2126 21U Portable Rolling Rack with Locking Front & Rear Doors

Overview

The Middle Atlantic PTRK-2126 is a 21U portable rolling rack built for integrators and AV/IT teams who need secure, mobile equipment transport without sacrificing the structural integrity of a permanent installation rack. At 500 lbs rated weight capacity and 24.5 inches of usable depth, the PTRK-2126 handles real-world gear loads — NVRs, managed switches, UPS units, patch panels — without the compromises you see on lighter-duty portable enclosures. If you're staging equipment for a trade show, deploying a temporary command center, or moving a rack between job sites, this is the unit designed for that workflow.

The PTRK-2126 (often searched as PTRK 2126) ships as a drop-ship item direct from Middle Atlantic, so lead time planning matters — confirm availability before committing it to a project schedule. It's TAA-compliant, which means it qualifies for federal, state, and municipal procurement vehicles where country-of-origin requirements apply.

For permanent rack deployments, browse the broader rack enclosures category. If you're also sourcing the NVR or switching gear that goes inside, the network video recorder selection and managed PoE switches pair naturally with this enclosure.

Key Features

• 21 Rack Units / 36.75 in Usable Height: 21U of usable rail space gives you room for a meaningful system — figure a 16-channel NVR (2U), a 24-port PoE switch (1U), a patch panel (1U), a UPS (2U), and you still have 15U to work with. The 36.75 in usable height is the number to measure against your gear stack, not the 45.91 in overall cabinet height.
• 500 lb Weight Capacity: Most portable rolling racks tap out at 200–300 lbs. The 500 lb rating here means you can load this rack the way you'd load a fixed floor-mount cabinet — dense UPS units, multi-drive NVRs, stacked servers — without worrying about caster or frame failure during a move.
• 24.5 in Usable Depth: The 24.5 in usable depth accommodates full-depth 1U/2U servers and most enterprise-class NVRs. Overall external depth is 26.93 in — the delta accounts for door swing and rail hardware. Measure your deepest piece of gear against 24.5 in before loading.
• Locking Front & Rear Doors: Both doors lock, which matters for temporary deployments in semi-public spaces — event floors, construction trailers, shared equipment rooms. Physical access control on both sides also means cable management at the rear isn't visible or accessible without a key.
• 10-32 Rack Rail Threading: Standard 10-32 tapped rails mean off-the-shelf rack screws, cage nuts, and mounting hardware work without adapters. No proprietary fasteners, no sourcing headaches on short-notice jobs.
• TAA-Compliant (Country of Origin: Mexico): TAA compliance is a hard requirement on many government and education contracts. The PTRK-2126 meets it. Federal origin is Mexico, which satisfies TAA designated-country rules. Verify against your specific contract vehicle if procurement compliance is a gating factor.
• 22.59 in Width: Standard 19-in rack rail spacing inside a 22.59 in overall width enclosure. The added width over the rack rail span accommodates side panels and door hardware without forcing non-standard gear configurations.

Integration & Compatibility

The PTRK-2126 fits standard 19-in rackmount equipment across surveillance, AV, and IT categories. The 10-32 tapped rail system is compatible with the full range of Middle Atlantic rack accessories — shelves, blanks, power strips, and cable management panels — so you can outfit the interior with the same parts you'd use in a fixed installation. Rolling casters make repositioning practical on smooth surfaces; confirm floor load ratings at your deployment site if the loaded rack will approach the 500 lb capacity ceiling.

For integrators building out surveillance infrastructure, pair this rack with rack-mount NVRs, PoE switches, and a rack-mount UPS to create a self-contained, transportable system. Review the rack accessories lineup for blanking panels, PDUs, and cable management to finish the build cleanly.

Frequently Asked Questions

Q: Is the Middle Atlantic PTRK-2126 TAA-compliant for government procurement?

A: Yes. The PTRK-2126 is TAA-compliant with a Federal Operations Country of Origin of Mexico, which is a TAA designated country. It qualifies for federal, state, and local government contract vehicles that require TAA compliance.

Q: What is the actual usable rack depth on the PTRK-2126?

A: Usable depth is 24.5 inches (62.2 cm). The overall external depth is 26.93 inches — the difference accounts for door hardware and rail mounting. Measure your deepest rackmount equipment against 24.5 inches to confirm fit.

Q: How much weight can the PTRK-2126 support?

A: The PTRK-2126 is rated for 500 lbs (226.8 kg) of equipment load. This is significantly higher than typical portable rolling racks, making it suitable for dense configurations with UPS units, NVRs, and servers.

Q: What rack rail thread type does the PTRK-2126 use?

A: The PTRK-2126 uses standard 10-32 tapped rack rails. Standard 10-32 rack screws work without adapters or proprietary hardware.

Q: Does the PTRK-2126 ship directly or from stock?

A: The PTRK-2126 is a drop-ship item fulfilled directly from Middle Atlantic. Confirm availability and lead time before committing to a project schedule with a hard install date.

Q: What is the usable rack unit height of the PTRK-2126?

A: The PTRK-2126 provides 21 rack units (RU) of usable space, with a usable interior height of 36.75 inches (93.3 cm). The overall cabinet height is 45.91 inches.

Ted Perry

The spec that separates the PTRK-2126 from cheaper portable rolling options is the 500 lb weight capacity — when you're loading this for a surveillance deployment with a multi-drive NVR, a managed PoE switch, and a rack-mount UPS, you'll clear 200 lbs before you're halfway full. Most portable racks that look similar on paper are rated at half that, and you feel it in the frame flex when you push them across a loading dock.

Technical Highlights:

• 500 lb Capacity: Dense security rack builds — NVR (30–50 lbs), UPS (40–80 lbs), switches, patch panels — load up fast. The 500 lb rating means you're not compromising the equipment list to stay under a weight ceiling.
• 24.5 in Usable Depth: Accommodates full-depth 1U/2U servers and enterprise NVRs. The 2.43 in difference between usable and external depth is accounted for by door hardware — not a surprise at installation.
• 10-32 Tapped Rails: No cage-nut conversion needed. Standard 10-32 hardware from any rack supply house works directly, which matters when you're assembling on-site on a deadline.

Deployment Considerations:

• Drop-ship fulfillment means the PTRK-2126 doesn't move through a local warehouse — build lead time into the project schedule and don't wait until the week of install to order.
• The overall cabinet height is 45.91 in, but usable height is 36.75 in — that gap isn't wasted space, it's the top cap, caster base, and door hardware. Don't plan your 21U equipment stack and then discover the physical footprint clears a 7-foot door frame by less than an inch.

For temporary command centers, event production builds, or staged security system deployments where the rack needs to travel between sites intact and locked, the PTRK-2126 is the right specification — the combination of 500 lb capacity, dual locking doors, and TAA compliance covers the load, the security, and the procurement requirements in a single SKU.
