Middle Atlantic ERK-4020 - 40SP 20D Stand-Alone Rack
Product Overview
The Middle Atlantic ERK-4020 is a 40-space, 20-inch deep ERK series stand-alone rack enclosure. The ERK series is one of Middle Atlantic's most widely deployed rack lines, offering a balanced combination of capacity, depth, and cost-effectiveness for commercial AV and IT infrastructure applications. The 20-inch depth profile makes this rack well suited for equipment rooms where floor space is constrained but a full 40U of capacity is required.

Product Description
The ERK-4020 provides 40U of standard rack space in a 20-inch deep welded steel enclosure. While shallower than the ERK-4425LRD (25-inch depth), the 20-inch profile accommodates the majority of AV signal processing, control, and networking equipment commonly deployed in commercial installations. The ERK series is designed to accept Middle Atlantic's extensive accessory catalog including doors, side panels, top sections, and power management.

FAQ
- What equipment fits in a 20-inch deep rack?
- Most standard AV and IT equipment with depths up to 18-19 inches fits comfortably in the ERK-4020. Verify individual equipment depths before specifying; very deep amplifiers or server units may require the ERK-4425LRD with 25-inch depth.
- Does the ERK-4020 include doors?
- Door configurations vary by model designation. Verify included accessories at purchase or contact Creation Networks for a complete specification.
- How does the ERK-4020 compare to the ERK-4425LRD?
- The ERK-4020 offers 40U at 20-inch depth. The ERK-4425LRD provides 44U at 25-inch depth with no rear door. Choose the ERK-4020 for shallower equipment loads; choose the ERK-4425LRD for deeper equipment or when additional U space is needed.
- Can the ERK-4020 be expanded with a top section?
- Yes. Middle Atlantic offers top extension sections compatible with the ERK series for installations requiring additional rack space above the standard unit height.
