Middle Atlantic 35SP/28D Rack W/rear DR - ERK-3528

Middle Atlantic ERK-3528 35U Floor-Standing AV Rack with Rear Door

Overview

The Middle Atlantic ERK-3528 is a 35U floor-standing open-frame rack with an integrated rear door, built for AV equipment rooms, network closets, and surveillance head-end installations where you need structured cable management and physical access control behind the enclosure. At 28 inches deep with 26.47 inches of usable depth, it accommodates full-depth NVRs, patch panels, and power distribution units without crowding — a real constraint when you're stacking multiple 2U recorders in a security operations room. The steel construction with black wrinkle powder coat finish handles the weight loads typical of dense surveillance back-end builds: UL-rated to 2,500 lbs, so a fully loaded NVR stack with storage expansion isn't a concern. TAA compliant and manufactured in the USA, the ERK-3528 qualifies for federal and government procurement projects where country-of-origin documentation is required. Ships flat for easier freight handling into finished equipment rooms.

Compatibility

Accepts any standard 19-inch panel-width equipment on 10-32 threaded rack rails — the universal fastener standard used across Middle Atlantic rack accessories, network video recorders, PoE switch chassis, patch panels, and AV amplifiers. The 35 RU capacity suits mid-to-large surveillance head-end builds combining an NVR, managed PoE switches, UPS, and structured cabling in a single enclosure. At 22 inches wide overall and 65.38 inches tall, verify floor clearance and door-swing radius before placement in tight IDF rooms. Compatible with Middle Atlantic's standard rack accessories line — shelves, blanks, fan panels, and power strips designed for the ERK series use standard 10-32 hardware.

Installation Notes

The ERK-3528 ships flat — factor assembly time into your installation schedule; this is not a roll-in-ready enclosure. 10-32 rack rail threads are the standard for this frame; confirm fastener type before ordering cage nut kits or pre-threaded rail accessories. The rear door is included in the frame-only configuration, but no PDU, blanking panels, shelves, or cable managers are included — order those separately. Seismic load capacity is UL listed, making it suitable for installations in seismic zones where rack bracing compliance is required by code. Product weight is 108.1 lbs unloaded; plan for two-person installation when positioning on raised floors or in congested equipment rooms.
