Middle Atlantic 35SP/28D Rack Less R DR - ERK-3528LRD

Middle Atlantic ERK-3528LRD 35U Open-Frame Floor-Standing AV Rack

Overview

The Middle Atlantic ERK-3528LRD is a 35U, 28-inch-deep open-frame floor-standing rack built for AV, security, and IT equipment deployments where airflow, accessibility, and structural integrity take priority over enclosure. At 65.38 inches tall with 61.38 inches of usable height and 26.47 inches of usable depth, the ERK-3528LRD accommodates full-depth NVRs, servers, patch panels, and AV signal processors without the clearance compromises of a shallow frame. The steel construction with black wrinkle powder coat finish handles demanding installations — including government and federal projects that require TAA compliance and domestic manufacturing (country of origin: USA). The open-frame design is the right call when front and rear equipment access matters more than dust containment, and when you need unobstructed cable routing without door clearance constraints.

Compatibility

Accepts standard 19-inch EIA-310 rackmount equipment across all 35U of usable space. The 10-32 threaded rail system is compatible with virtually all commercial rackmount hardware — network video recorders, managed PoE switches, patch panels, UPS units, and AV signal distribution equipment. The 28-inch overall depth (26.47 inches usable) fits full-depth 1U and 2U servers, deep NVRs, and high-density switch chassis without overhang. This frame pairs directly with Middle Atlantic's ERK accessory line for rack accessories including side panels, blanks, and cabling guides. The rear-door-free configuration (no rear door included or available on this SKU) is appropriate for equipment bays with rear-wall cable management or flush-mount applications. For deployments requiring rear door protection, evaluate a different ERK variant with door option.

Installation Notes

Ships assembled — not flat-packed — so verify elevator and doorway clearance before delivery; the 65.38-inch assembled height and 125 lb shipping weight require two-person handling. UL-listed seismic load capacity with ASCE rating makes this suitable for security rack deployments in seismic zones where rack tie-down certification is required by local code. The 2,500 lb UL load rating means equipment weight is unlikely to be a limiting factor in any realistic deployment. Mount to a level, solid floor surface; use appropriate leveling feet or casters from the Middle Atlantic accessory line if the installation surface is uneven. Standard 10-32 cage nuts and screws are required for equipment mounting — not included. TAA compliance supports GSA schedule and federal procurement without additional sourcing documentation.
