Middle Atlantic 12SP Cabinet Frame RK 20D - CFR-12-20

Middle Atlantic CFR-12-20 12U Cabinet Frame Rack, 20-Inch Deep

Overview

The Middle Atlantic CFR-12-20 is a 12U open-frame cabinet rack built for in-cabinet installations where you need a rigid, standards-compliant mounting structure without the bulk of a full enclosure. At 20 inches of usable depth and a UL-listed 250 lb load capacity, the CFR-12-20 handles dense AV and security equipment loads — NVRs, patch panels, PoE switches, and power distribution units — in wiring closets, server rooms, and rack enclosures where space is constrained. Steel construction with a flat black powder coat finish keeps it professional in any install environment. TAA compliant and manufactured in the USA, making it a fit for government and federal procurement projects where country-of-origin matters.

Compatibility

The CFR-12-20 uses standard 10-32 threaded rack rails, accepting any rack-mount equipment built to the EIA-310 19-inch standard. It fits within Middle Atlantic's CFR-series cabinet enclosures and is compatible with the full range of Middle Atlantic rack accessories — blanking panels, cable managers, and mounting hardware designed for the CFR frame system. With 19.25 inches of overall width and 21 inches of usable height across 12 rack units, it accommodates virtually all 1U through 4U rack-mount security and AV equipment on the market. If you're building out a network video recorder deployment or a structured cabling bay, the 20-inch depth suits standard 1U NVRs, managed PoE switches, and typical 1U patch panels without overhang issues.

Installation Notes

The 10-32 rail thread pattern requires 10-32 cage nuts or matching screws — not included; verify your mounting hardware before install. Product weight is 19.1 lbs (8.7 kg) with a shipping weight of 24.6 lbs (11.2 kg), so single-person install into an overhead position is feasible but plan accordingly. The UL-listed 250 lb load rating applies to static vertical loading per UL certification; do not exceed this figure across all installed equipment. Overall height of 21.94 inches should be confirmed against your enclosure's interior clearance before ordering — the usable rack height is 21 inches (12 RU at 1.75 inches each).
