Middle Atlantic 27SP/28D Rack W/rear DR - ERK-2728

Middle Atlantic ERK-2728 27U Floor-Standing AV Rack with Rear Door

Overview

The Middle Atlantic ERK-2728 is a 27U floor-standing steel rack engineered for security and AV infrastructure deployments where structural integrity and serviceability are non-negotiable. At 28 inches deep with a rear door included, it handles dense NVR, server, and switching builds that need front-and-rear access without improvising a separate enclosure. If you're specifying rack infrastructure for a network video recorder stack or a multi-switch security core, this is the rack to price first.

Built in the USA and TAA-compliant, the ERK-2728 ships as a frame-only configuration — meaning you're not paying for pre-populated accessories you don't need, and you can outfit it precisely to your application with compatible panels, shelves, and cable management from the Middle Atlantic rack and enclosure line.

Key Features

• 27 Rack Units of Usable Space (47.38" usable height): 27U accommodates a fully loaded NVR stack — multiple recorders, a PoE switch, a UPS module, and patch panels — without stacking two half-height racks or leaving gear on the floor. The 47.38-inch usable height means you're not losing meaningful RU to structural crossbars.
• 28" Depth / 26.47" Usable Depth: The 28-inch overall depth (26.47 inches usable) provides clearance for deep 1U and 2U servers, full-depth UPS units, and cable-heavy NVR appliances. Cramped 24-inch racks force cable bend-radius compromises; this one doesn't.
• 2500 lb UL-Listed Load Capacity: UL-listed at 2500 lbs — not a marketing claim, a certified rating. A fully populated 27U rack with NVRs, hard drive arrays, and switching gear rarely exceeds 800 lbs; this rating means the frame will not be the weak link even in worst-case dense configurations.
• Seismic-Rated per UL and ASCE Standards: The seismic rating matters in California, the Pacific Northwest, and any jurisdiction adopting IBC seismic provisions. If your AHJ requires seismic compliance for IT/security equipment enclosures, this rack passes — that's a spec to have in the submittal package before the inspector asks.
• 10-32 Rack Rail Threading: Standard 10-32 threaded rails are compatible with virtually all commercial NVR, server, and networking equipment. You won't need cage nut adapters for most equipment — square-hole racks require them universally; 10-32 rails often don't.
• Rear Door Included: The rear door is not an optional add-on here — it ships with the rack. In a security operations room or IT closet with multiple personnel, a rear door prevents accidental cable pulls and keeps the installation looking finished without a separate purchase order line item.
• Black Wrinkle Powder Coat Finish: Wrinkle powder coat resists minor contact damage better than smooth finishes — relevant in active installation environments where panels and rails get slid in and out repeatedly over the rack's service life.
• TAA-Compliant, USA-Made: Federal Ops Country of Origin is USA. TAA compliance is satisfied, making this rack eligible for GSA schedules and government contract work where country-of-origin documentation is required.
• 19" Panel Width: Standard EIA 19-inch panel width ensures compatibility with the entire universe of rackmount equipment. No adapters, no surprises.
• 100.1 lb Product Weight (132 lb Shipping Weight): At 100 lbs unloaded, this is a two-person installation. Budget accordingly for labor — solo rack positioning on a finished floor risks tipping and floor damage.

Integration & Compatibility

The ERK-2728 accommodates standard 19-inch EIA rackmount equipment with 10-32 threaded rails. It is compatible with Middle Atlantic's full range of rack accessories including blanking panels, vented shelves, cable management, and PDU mounting hardware. The frame-only configuration makes it the correct base for custom builds — pair it with a dedicated rackmount UPS and a managed PoE switch when building a complete security infrastructure enclosure. For large multi-rack deployments, consult Middle Atlantic's accessory ecosystem for rack-to-rack joining hardware and grounding kits. The 22-inch overall width (55.9 cm) is the standard footprint for free-standing rack planning — confirm floor tile cutout or cable chase routing before positioning.

TAA compliance and seismic certification make the ERK-2728 a direct fit for government and federal security deployments where procurement and installation standards demand both. Keep the product data sheet in your submittal package — the UL seismic listing and TAA documentation are verifiable on the Middle Atlantic/Legrand AV product page.

Frequently Asked Questions

Q: Is the Middle Atlantic ERK-2728 TAA compliant?

A: Yes. The ERK-2728 is TAA-compliant with a Federal Ops Country of Origin of USA, making it eligible for GSA schedule procurement and government contract deployments.

Q: What is the load capacity of the ERK-2728?

A: The ERK-2728 carries a UL-listed load capacity of 2,500 lbs (1,134 kg). This is a certified UL rating, not a manufacturer estimate.

Q: Is the ERK-2728 seismic rated?

A: Yes. The ERK-2728 is UL-listed for seismic load capacity and ASCE-compliant, making it suitable for deployments in seismic zones where IBC or jurisdiction-specific seismic compliance is required for IT and security equipment enclosures.

Q: Does the rear door come included with the ERK-2728?

A: Yes. A rear door is included with the ERK-2728 as part of the standard configuration — it is not a separately ordered accessory.

Q: What rack rail type does the ERK-2728 use?

A: The ERK-2728 uses standard 10-32 threaded rack rails with a 19-inch panel width, compatible with the vast majority of commercial NVR, server, and networking equipment without cage nut adapters.

Q: What are the usable dimensions inside the ERK-2728?

A: The ERK-2728 provides 26.47 inches (67.2 cm) of usable depth and 47.38 inches (120.4 cm) of usable height across 27 rack units.

Jerry Tildsen

When I spec a security infrastructure rack for a mid-size commercial deployment, the first thing I check is UL load certification and whether the depth clears full-size UPS units — the ERK-2728 answers both with a 2,500 lb UL-listed rating and 26.47 inches of usable depth. That combination is not universal in this product class, and it's why I reach for this model when the equipment list includes anything heavier than light switching gear.

Technical Highlights:

• UL-Listed 2,500 lb Load Capacity: Certified, not claimed — this is the number to put on your submittal when the GC asks about rack structural ratings on a government or healthcare job.
• Seismic Rating (UL + ASCE): If you're installing in California or any IBC seismic zone, this clears the AHJ hurdle before it becomes a punch-list item. Not every 27U rack in this price tier carries a legitimate seismic listing.
• 26.47" Usable Depth at 28" Overall: Full-depth NVR appliances and 2U UPS units fit without forcing cable management compromises. The 1.53-inch difference between overall and usable depth is tight and efficient — you're not losing RU depth to unnecessary structural elements.

Deployment Considerations:

• At 100.1 lbs unloaded (132 lbs shipping), this is a two-person lift for positioning — plan labor accordingly, especially on elevated floors or finished raised-access installations where tipping risk is real.
• Frame-only configuration means blanking panels, PDU mounting, and cable management are separate line items — budget for them upfront rather than discovering gaps during punch-list walkthrough.

The ERK-2728 is the correct call for a government facility, healthcare operations center, or seismic-zone commercial security room where the combination of TAA compliance, UL seismic certification, and deep usable space all need to be on the same submittal sheet.
